The problem of weighted H∞ model reduction for continuous time-delay switched system is considered. The delay-dependent approaches are used to construct a reduced- order stable system such that the error system with respect to a given delay switched system is exponentially stable and has a prescribed weighted H∞ performance. The average dwell time approach and the linear matrix inequality (LMI) technique...
This paper is concerned with the stability analysis for a class of networked control systems (NCS) with large and time-varying delays. By choosing proper Lyapunov-Krasovskii functionals and using a descriptor model transformation of the system, LMI-based sufficient conditions for the stability are derived. Numerical examples are included to illustrate the effectiveness of the proposed approach
This paper presents delay-dependent robust H∞ controller design for a class of uncertain linear systems with a time-varying discrete delay and a constant distributed delay. The parameter uncertainties are assumed to reside in a polytope. Designing a linear memoryless state feedback H∞ controller, and a sufficient condition with delay-dependent is derived for the robust asymptotic stability of the...
This paper is concerned with the problems of delay-dependent robust Hscrinfin and Lscr2-Lscrinfin filtering for a class of linear parameter varying (LPV) systems with both discrete and distributed delays. The distributed delays are assumed to appear in both the state and measurement equations. Our attention is focused on the design of delay-dependent robust full-order filters, which guarantee the...
This paper investigates robust fault detection and isolation problem for a class of discrete-time Markovian jump systems with mode-dependent time-delays and norm-bounded uncertainties. Attention is focused on constructing the residual generator based on the filter whose parameters depend on the system modes and formulating fault detection and isolation filter design as Hinfin filtering problem. The...
The robust stability and robust sliding mode control problems are studied for a class of linear distributed delay systems with polytopic-type uncertainties in this paper by applying the parameter-dependent Lyapunov functional approach combining with a new method of introducing some relaxation matrices and tuning parameters, which can be chosen properly to lead to a less conservative result. First,...
This paper is concerned with the sliding mode observer design and observer-based controller design for a class of uncertain nonlinear distributed delay systems. According to the sliding mode control theory, first, a sufficient condition is proposed for robust asymptotic stability of the sliding mode dynamics. A sliding mode observer is designed, and at the same time, a sufficient condition is given...
This paper investigates robust fault detection problem for a class of discrete-time LPV systems with time-varying delays. Attention is focused on constructing the residual generator based on the filter whose parameters matrices depend on time-varying parameters, and formulating the design of fault detection filters as Hinfin filtering problem. The objective is to make the difference between the residual...
