    We present a Newton-like method for solving algebraic Riccati equations that uses an exact line search to improve the sometimes erratic convergence behavior of Newton's method. It avoids the problem of a disastrously large first step and accelerates convergence when Newton steps are too small or too long. The additional work to perform the line search is small relative to the work needed to calcul... View full abstract»

    We consider a system described by the one-dimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end of the system. The transfer function of the proposed controller is a proper rational function of the complex variable and may contain a single pole at the origin and a pair of c... View full abstract»

    This paper addresses the sensitivity analysis of stochastic Petri nets (SPNs) using simulations. The goal is to evaluate the derivatives of performance measures with respect to timing parameters. To characterize the underlying stochastic processes of SPNs, we use a generalized semi-Markov process (GSMP) representation and propose a new representation, called GSMP*, which differs from GSMP in the r...

    The main objective of this paper is to solve the following stabilizing output feedback control problem: given matrices (A; B2 ; C2) with appropriate dimensions, find (if one exists) a static output feedback gain L such that the closed-loop matrix A-B2LC2 is asymptotically stable. It is known that the existence of L is equivalent to the existence of a pos... View full abstract»

  • Insensitive static-state feedback stabilization of a class of single-input linear systems by the condition numbers

    Publication Year: 1998, Page(s):108 - 115

    The static-state feedback stabilization problem is considered for a class of single-input linear systems so that the closed-loop eigenvalues are as insensitive as possible to unstructured perturbations. Given a pair of complex conjugate numbers γ,γ * and a closed and bounded interval Γ of the real axis sufficiently far to the left of such a pair, a procedure for the de... View full abstract»

    In this paper, the problem of output feedback stabilization of linear systems with mismatched uncertainties is investigated. A new approach to the design of output feedback controller is proposed, and the respective output feedback gains are obtained through the solution of a Riccati equation with linear constraints. Solvability conditions for such a constrained Riccati problem are derived, and a ... View full abstract»

  • Adaptive motion/force control of multiple manipulators with joint flexibility based on virtual decomposition

    Publication Year: 1998, Page(s):46 - 60
    Cited by:  Papers (5)

    In this paper, a virtual decomposition-based adaptive motion/force control scheme is presented to deal with the control problem of coordinated multiple manipulators with flexible joints holding a common object in contact with the environment. The control scheme is essentially a generalized Newton-Euler approach in which the original system is virtually decomposed into several subsystems, including... View full abstract»

    A mixed parametric-nonparametric approach to H identification is proposed, aimed at estimating a low-order approximating model and an identification error giving a measure of the model perturbation in a form well suited for H control methodologies. It is shown how to estimate the modeling errors of the identified parametric model and how to evaluate the performa... View full abstract»

  • A parametrization of all the unfalsified plant models for MIMO systems

    Publication Year: 1998, Page(s):18 - 30

    The results of the parametrization of all the unfalsified models for single-input/single-output systems are extended to multi-input/multi-output (MIMO) systems. In this parametrization, the assumed a priori plant and noise information are upper bounds of the H -norm of the plant matrix-valued transfer function and the noise magnitude. The parametrization is on the basis of severa... View full abstract»

    We propose a very general framework that systematizes the notion of a hybrid system, combining differential equations and automata, governed by a hybrid controller that issues continuous-variable commands and makes logical decisions. We first identify the phenomena that arise in real-world hybrid systems. Then, we introduce a mathematical model of hybrid systems as interacting collections of dynam... View full abstract»

    For a class of singie-input/single-output uncertain nonlinear systems, affected both by uncertain time-varying parameters (with known bounds) and unknown time-varying bounded disturbances, a new robust adaptive state-feedback control algorithm is presented. It guarantees: boundedness of all signals and arbitrary disturbance attenuation when both disturbances and time-varying parameters are present... View full abstract»

    In this paper we consider the mixed H2/H-control problem for the class of discrete-time linear systems with parameters subject to Markovian jump linear systems. It is assumed that both the state variable and the jump variable are available to the controller. The transition probability matrix may not be exactly known, but belongs to an appropriate convex set. For this ... View full abstract»

  • Discrete-event control of nondeterministic systems

    Publication Year: 1998, Page(s):3 - 17

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (564 KB)

    Nondeterminism in discrete-event systems occurs in many practical situations and often as a result of partial observability of events. For the adequate description of nondeterministic systems and nondeterministic phenomena, the trajectory-model formalism was introduced by Heymann (1991) and Heymann et al. (1991). This formalism has been used in by Shayman et al. (1995) for obtaining various result... View full abstract»

  • A general class of sliding surface for sliding mode control

    In the conventional sliding mode control, the relative degree of the chosen sliding surface is usually one. This paper addresses a general class of sliding surface whose relative degree is no longer restricted to one. We show that when the relative degree is more than two, it is inevitable that there will exist a limit cycle for the nonlinear sign function. And for the case of relative degree two ...

    This paper presents results obtained for the control of set-valued discrete-time dynamical systems. Such systems model nonlinear systems subject to persistent bounded noise. A robust control problem for such systems is introduced. The problem is formulated as a dynamic game, wherein the controller plays against the set-valued system. Both necessary and sufficient conditions in terms of (stationary... View full abstract»
