Recently the control of hybrid system has attracted many research efforts. However, few studies have been made on hybrid systems with unknown parameters. In this paper, adaptive controller design is explored for a class of hybrid systems called piecewise linear systems, based on the concept of the polynomial constraints which can decouple the model parameters from the inference of the discrete state...
In this paper, we present a robust recursive filtering algorithm for discrete time-varying systems with sensor failures and uncertain parameters in their state space models. The exiting results are generalized to the case where each sensor may fail at any sample time independently of the others. For robust performance, stochastic parameter uncertainties are included in the system matrix. The design...
This paper is concerned with the robust Hinfin filtering problem for a class of uncertain nonlinear networked systems with both multiple stochastic time-varying communication delays and multiple packet dropouts. The discrete-time system under consideration is also subject to parameter uncertainties, state-dependent stochastic disturbances and sector-bounded nonlinearities. Sufficient conditions are...
The Hinfin control problem is studied in this paper for networked control systems (NCSs) with short time-varying delays. By considering state feedback controllers, the closed-loop NCS is described as a discrete-time linear uncertain system model, and the uncertain part reflects the effect of the variation nature of the network-induced delays on the system dynamics. Then, a sufficient condition is...
This paper discusses robust stability and stabilization of uncertain discrete-time fuzzy systems that have time-varying delay in state. There have been only a few results on stability and stabilization for discrete-time fuzzy time-delay systems. Especially, few results on robust stability and stabilization for a class of uncertain discrete-time fuzzy time-delay systems have appeared in the literature...
This paper deals with the problem of reliable control against controller failure for a class of uncertain discrete time systems with both state and input delay. The considered system is modeled as uncertain discrete switched system with stable and unstable subsystem. Based on average dwell time method, the sufficient conditions of exponential stability for system are given in terms of linear matrix...
