    This paper concerns the H-infinity control problem of a coupled transport-diffusion system with Neumann boundary condition, related to parallel-flow heat exchange process. It is shown that, by using the previous approach for a single diffusion system, the H-infinity control problem can be solved by constructing a residual mode filter (RMF)-based controller which is of finite-dimension. A numerical simulation result is given to demonstrate the validity of the proposed method.

    Background: In mathematical epidemiology, age-structured epidemic models have usually been formulated as the boundary-value problems of the partial differential equations. On the other hand, in engineering, the backstepping method has recently been developed and widely studied by many authors. Methods: Using the backstepping method, we obtained a boundary feedback control which plays the role of the threshold criteria for the prediction of increase or decrease of newly infected population. Under an assumption that the period of infectiousness is same for all infected individuals (that is, the recovery rate is given by the Dirac delta function multiplied by a sufficiently large positive constant), the prediction method is simplified to the comparison of the numbers of reported cases at the current and previous time steps. Results: Our prediction method was applied to the reported cases per sentinel of influenza in Japan from 2006 to 2015 and its accuracy was 0.81 (404 correct predictions to the total 500 predictions). It was higher than that of the ARIMA models with different orders of the autoregressive part, differencing and moving-average process. In addition, a proposed method for the estimation of the number of reported cases, which is consistent with our prediction method, was better than that of the best-fitted ARIMA model ARIMA(1, 1, 0) in the sense of mean square error. Conclusions: Our prediction method based on the backstepping method can be simplified to the comparison of the numbers of reported cases of the current and previous time steps. In spite of its simplicity, it can provide a good prediction for the spread of influenza in Japan.

    This paper is concerned with the exponential stability of heat exchangers with delayed boundary feedback. Especially, heat exchangers of counter-flow type/parallel-flow type are treated, where they are respectively described by a coupled hyperbolic equations with time lag in the boundary feedback loop. When time lag does not exist, the exponential stability has been shown for counter-flow type by using the port Hamiltonian approach as well as the spectral analysis, and the conditions for the exponential stability to be assured are given. In this paper, time lag is expressed by using a transport equation, and the port Hamiltonian approach is applied to the whole system. A condition for the system with time lag to be exponentially stable is derived for counter-flow type and parallel-flow type.

    In this paper, we discuss the problem of approximating stability radius appearing in the design procedure of finite-dimensional stabilizing controllers for an infinite-dimensional dynamical system. The calculation of stability radius needs the value of H-infinity-norm of a transfer function whose realization is described by infinite-dimensional operators in a Hilbert space. From the computational point of view, we need to prepare a family of approximate finite-dimensional operators and then to calculate the H-infinity-norm of their transfer functions. However, it is not assured that they converge to the value of H-infinity-norm of the original transfer function. The purpose of this study is to justify the convergence. In a numerical example, we treat parabolic distributed parameter systems with distributed control and distributed/boundary observation.

    This paper is concerned with the problem of stabilizing one-dimensional parabolic systems related to formations by using finite-dimensional controllers of a modal type. The parabolic system is described by a Sturm-Liouville operator, and the boundary condition is different from any of Dirichlet type, Neumann type, and Robin type, since it contains the time derivative of boundary values. In this paper, it is shown that the system is formulated as an evolution equation with unbounded output operator in a Hilbert space, and further that it is stabilized by using an RMF (residual mode filter)-based controller which is of finite-dimension. A numerical simulation result is also given to demonstrate the validity of the finite-dimensional controller.

    In this paper, we study the finite-dimensional stabilization problem of the cascade consisting of the one-dimensional transport-diffusion process and an unstable Ordinary Differential Equation ( ODE) plant, where the ODE plant is connected with the transport-diffusion process through a filter. The input to the whole system is only Dirichlet boundary input to the transportdiffusion process, and the outputs are the Dirichlet data at the boundary of process domain and the output from the ODE plant. In this paper, we use the latest method and show that the one-dimensional transport-diffusion process with such input and output can be formulated as a system with A.-bounded output operator and direct feedthrough term. It is shown that, under the assumption that the ODE plant is controllable and observable, the finite-dimensional model of the whole system becomes controllable and observable, when the filter mentioned above is a Residual Mode Filter ( RMF). This fact enables us to construct a finite-dimensional stabilizing controller by using an RMF approach.

    This paper is concerned with observability and the related problem for a parallel flow two-fluid heat exchanger equation with diffusive terms. The observability results are stated under two kinds of boundary observations and the eigenvalues of the observability gramians are discussed. When one considers the inverse problem of estimating the initial states under the observations, it is expected that the reconstruction of the initial states under the observation at one outlet becomes more difficult than that under the observation at two outlets, from the physical point of view. The purpose of this paper is to explain the intuitive fact by using the eigenvalues of the observability gramians.

    We investigate the problem of enhancing the stability of a coupled transport-diffusion system with Dirichlet actuation and Dirichlet measurement. In the recent paper [H. Sano, Neumann boundary control of a coupled transport-diffusion system with boundary observation, J. Math. Anal. Appl. 377 (2011) 807-816], we treated the stabilization problem for the case with Neumann actuation and Dirichlet measurement, where the variable transformation of the state is performed by using the fractional power of an unbounded operator. However, we cannot use the similar transformation for the case with Dirichlet actuation and Dirichlet measurement, since it brings an ill-posed expression of the system. So, we use an algebraic approach for the formulation of the system. In this paper, it is shown that a reduced-order model with a finite-dimensional state variable is controllable and observable. The fact enables us to construct a finite-dimensional stability-enhancing controller for the original infinite-dimensional system by using a residual mode filter (RMF) approach. The novelty of this paper is the structure that the controller contains the dynamics with respect to the control variable. As a result, the state vector of the resulting closed-loop system includes the control variable as its entry. (C) 2011 Elsevier Inc. All rights reserved.

    In this paper, we consider an output tracking problem of a parallel-flow heat exchange process with distributed and boundary inputs. As the distributed inputs to the system, the output feedback control is first applied. Under zero boundary inputs, it is shown that the C(0) -semigroup describing the closed-loop system satisfies the spectrum determined growth condition. Next, we apply a backstepping method to the design of the boundary inputs for output tracking. Our main result shows that the output of the system reaches a reference signal in finite time under both the output feedback control and the boundary control law derived by the backstepping method.

    We study the Neumann boundary stabilization problem of a coupled transport-diffusion system in the case where the observation is done at the boundary. In the recent paper of Sano and Nakagiri [H. Sano, S. Nakagiri, Stabilization of a coupled transport-diffusion system with boundary input, J. Math. Anal. Appl. 363 (2010) 57-72], we treated the stabilization problem for the case with Neumann boundary control and distributed observation. The novelty of this paper is the formulation of the boundary observation equation in a Hilbert space. We have an interesting result of its being expressed by using an A(1)(gamma)-bounded operator with gamma epsilon (1/2, 1). Moreover, it is shown that a reduced-order model with a finite-dimensional state variable is controllable and observable. This means that one can always construct a finite-dimensional stabilizing controller for the original infinite-dimensional system by using a residual mode filter (RMF) approach.

    We consider the problem of stabilizing a coupled transport-diffusion system with boundary input. The system is described by two linear transport-diffusion equations and is not asymptotically stable. In order to stabilize the system with boundary input, sensor influence functions are assumed to be located at interior of the domain. First, we formulate the system as an evolution equation with unbounded output operators in a Hilbert space, using variable transformation. Next, we derive a reduced-order model with a finite-dimensional state variable for the infinite-dimensional system. Then, a stabilizing controller is constructed for the reduced-order model under an additional assumption. It is shown that the finite-dimensional controller together with a residual mode filter plays a role of a finite-dimensional stabilizing controller for the original infinite-dimensional system, if the order of the residual mode filter is chosen sufficiently large. Finally, the validity of the design method is demonstrated through a numerical simulation. (C) 2009 Elsevier Inc. All rights reserved.

  • Feedback Control of Parallel-Flow Heat Exchanger Equations Using a Forwardstepping Method

    In this paper, we treat feedback control of parallel-flow heat exchanger equations with distributed and boundary inputs. As the distributed inputs to the system, the output feedback control is first applied under zero boundary inputs. Then, it is shown that the C-0-semigroup describing the closed-loop system satisfies the spectrum determined growth condition. Next, we apply a forwardstepping method to the design of the boundary inputs. Our main result shows that, for any initial data belonging to a linear space, the solution of the system becomes zero in finite time under both the output feedback control and the control law derived by the forwardstepping method.

Our main result shows that, for any initial data belonging to a linear space, the solution of the system becomes zero in finite time under both the output feedback control and the control law derived by the backstepping method. Further, the exact formula of feedback solutions is presented. Two applications to the parallel-flow heat exchange equations and the reactor equations of plug-flow type are given.

    This paper is concerned with the observability problem of a parallel-flow two-fluid heat exchanger equation with diffusion term. First, the case where two fluid temperatures are measured it the outlet is considered. It is shown that, the observed system with the measurements becomes observable oil any interval of time through a concrete series expression of the solution. Next, the two cases where each one of two fluid temperatures is measured at, the outlet, are considered. It is also shown that the observed system with the only one measurement, becomes observable on any interval of time except for the special cases of physical constant's appearing in the equation. For the exceptional cases the unobservable subspace is finite dimensional and is characterized by using the eigenfunctions of heat equation with fluid transfer term.

    In this paper, we treat the problem of stabilizing a flexible cable with two rigid loads which is described by two kinds of hyperbolic equations. From the engineering point of view, the model can be regarded as a distributed parameter overhead crane which conveys two loads simultaneously. In this, the mass of the cart is assumed to be not zero. After deriving a control law which does not increase an energy defined for the model, we prove the asymptotic stability of the closed-loop system by using the LaSalle's invariance principle. The stabilization problem is also discussed for the case of the system with one rigid load.

    This paper is concerned with the dynamical analysis of parallel-flow heat exchanger equations with observation at the outlet of tube/control at the inlet of tube. The parallel-flow heat exchanger equation is super-stable under zero boundary condition. The system can be described by an unbounded operator of lower triangular form through a variable transformation. By calculating a Co-semigroup generated by the operator, it is shown that the system is observable if both fluid temperatures are measured at the outlet, and that the system is observable with respect to the non-negative cone of the state space if either of them is measured at the outlet. Moreover, it is shown that the system is reachable if both fluid temperatures are controlled at the inlet, and that the system is reachable with respect to the non-negative cone of the state space if either of them is controlled at the inlet.

    An H-infinity control problem with measurement feedback for infinite-dimensional discrete-time (IDDT) systems whose homogeneous parts are described by Riesz-spectra operators is considered. The aim is to construct a finite-dimensional stabilizing controller for the IDDT system that makes the H-infinity norm of the closed-loop transfer function less than a given positive number delta. For that purpose, we first formulate the IDDT system as an IDDT system in l(2) and derive a finite-dimensional reduced-order system for the IDDT system in l(2). A stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than another positive number is then constructed for the reduced-order model. The finite-dimensional controller together with a residual mode filter plays a role of a finite-dimensional stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than delta for the original IDDT system, if the order of the residual mode filter is chosen sufficiently large.

    In this paper, we study H-infinity control of linear parabolic systems with unbounded output operators. Our aim is to construct a finite-dimensional stabilizing controller for the linear parabolic system that makes the H-infinity norm of the closed-loop transfer function less than a given positive number delta. To this end, we first derive a finite-dimensional reduced-order system for the linear parabolic system. Then, for the reduced-order model, we construct a stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than another positive number. It is proved that the finite-dimensional controller together with a residual mode filter plays a role of a finite-dimensional stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than delta for the original linear parabolic system, if the order of residual mode filter is chosen sufficiently large.

    In this paper, we consider H-infinity control of linear and semilinear diffusion systems by using a finite-dimensional controller. The main aim is to construct a finite-dimensional stabilizing controller for the linear diffusion system that makes the H-infinity norm of the closed-loop transfer function less than a given positive number delta. For that purpose, we first derive a finite-dimensional reduced-order system for the linear diffusion system. Then, a stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than another positive number is constructed for the reduced-order model. It is proved that the finite-dimensional controller, together with a residual mode filter, plays a role of a finite-dimensional stabilizing controller that makes the H-infinity norm of the closed-loop transfer function less than delta for the original linear diffusion system if the order of residual mode filter is chosen sufficiently large. Moreover, it is shown that the finite-dimensional H-infinity controller constructed for the linear diffusion system also works as a finite-dimensional H-infinity controller for a semilinear diffusion system with sufficiently small nonlinear term.

    The stabilization problem of infinite-dimensional systems with periodically time-varying bounded input and unbounded output operators is considered. The unboundedness of the periodically time-varying ouput operators is assumed to be A(gamma)-bounded. For example, the systems contain linear diffusion systems with boundary control and observation, where the actuator and sensor influence functions periodically vary with respect to the time variable. The aim of this paper is to show that a controller, which consists of a finite dimensional stabilizing controller constructed for the finite-dimensional reduced-order modal model and a residual mode filter, works as a finite-dimensional stabilizing controller for the original infinite-dimensional system if the order of residual mode filter is chosen to be sufficiently large.

    rn this paper, we consider H-infinity control of infinite-dimensional linear time-varying (IDLTV) systems whose homogeneous parts are of modal type, by using a finite-dimensional controller. The aim is to construct a finite-dimensional stabilizing controller for the IDLTV system that makes the norm of the closed-loop operator less than a given positive number delta. To this end, a finite-dimensional model is firstly derived for the IDLTV system, and a stabilizing controller that makes the norm of the closed-loop operator less than another positive number gamma(<delta) is constructed for the finite-dimensional model. Then it is shown that a controller, which consists of a residual mode filter and the controller mentioned above, becomes a finite-dimensional stabilizing controller for the given IDLTV system such that the closed-loop operator has norm less than delta, if the order of the residual mode filter is chosen sufficiently large.

  • AN APPLICATION OF INERTIAL MANIFOLD THEORY TO BOUNDARY STABILIZATION OF SEMILINEAR DIFFUSION-SYSTEMS

    H SANO, N KUNIMATSU

    This paper deals with an application of inertial manifold theory to boundary stabilization of semilinear diffusion systems on a one-dimensional domain. It is shown that a Sakawa type of controller plays an important role in the construction of an inertial manifold for the closed-loop system with a given semilinear diffusion system. This means that the use of a Sakawa type of controller reduces the stabilization problem for the closed-loop system to the one on the inertial manifold. (C) 1995 Academic Press, Inc.

    This paper is concerned with the stabilization problem of infinite-dimensional systems with A(gamma)-bounded output operators. An operator is said to be A(gamma)-bounded if it can be written as C(A + c)(gamma) for some bounded operator C and some scalar c (see [1]). For example, the linear diffusion system with distributed (or boundary) control and boundary observation is formulated as an evolution equation with bounded input operator and A(gamma)-bounded output operator in a Hilbert space. The purpose of this paper is to show that the closed-loop system with a finite-dimensional controller containing residual mode filter, which Balas introduced for infinite-dimensional systems with bounded input and output operators, is exponentially stable if the order of residual mode filter is chosen sufficiently large.

    The stabilization of semi-linear parabolic distributed systems by means of boundary controls is treated, formulating the partial differential equation describing the system as an evolution equation in a Hilbert space. Here, by using the properties of an analytic semigroup, the global existence of the solution under static output feedback is shown. Moreover, in the similar way, the global existence of the solution and the stabilizability for the system which installs a finite dimensional dynamic compensator is shown.

    This paper deals with the stabilization of semilinear parabolic distributed systems by means of boundary controls. The partial differential equation describing the system is formulated as a semilinear evolution equation in a Hilbert space by using a variable transformation. Here it is shown that the solution globally exists for the closed-loop system which installs a finite-dimensional dynamic compensator by using the properties of an analytic semigroup. Moreover, a sufficient condition for stabilization of the system is derived by making use of the modified Gronwall's inequality developed in this paper.
