“…The main reason for fault diagnosislaid which increasing demand for high reliability and safety in many actual engineering control systems [1][2][3]. A lot of fruitful results can be found recently, most design schemes of fault diagnosis architectures for dynamic system with linear system, nonlinear system and switched system [4][5][6]. For the switched systems, which exist in the practical systems widely, and the switched phenomenon exists in industrial control nature or in the life of people widely.…”

“…Xia et al (2010b) considered the robust adaptive sliding mode control for uncertain discretetime systems with time delay. In recent years, special attention has been paid to switched non-linear systems with time delay (Alwan and Liu and Yuan, 2011;Xiang and Chen, 2010;Xiang et al, 2011), and several useful results have been reported in the literature, such as the issues on stability analysis, robust control, H ' filtering, and so on.…”

This paper investigates the problem of tracking control for a class of switched non-linear systems with time-varying delay. Firstly, based on the average dwell time method, a new exponential stability criterion for a class of switched non-linear systems with time-varying delay is derived; it is shown that this new criterion can provide fewer conservative results than those in the existing references. Then, tracking control for the systems is investigated, and a kind of state feedback control law and switching signal are proposed to satisfy the H∞ model reference tracking performance. Finally, two numerical examples are given to illustrate the effectiveness of the proposed method.

“…The problem of robust fault detection for discrete-time nonlinear systems using Takagi-Sugeno fuzzy affine dynamic models is studied in [27]. Fault estimation of switched nonlinear systems of neutral types has been proposed in [28]. Also, a fault-tolerant control scheme for nonlinear networked control systems has been analyzed in [2].In the context of nonlinear systems, there have been a number of interesting results proposed for the fault detection problems.…”

SUMMARYThis paper is concerned with the H 1 fault estimation for a class of discrete-time switched nonlinear systems with mixed time delays. The fault existing in the system is assumed to be characterized by an external system, which incorporates the fault's prior knowledge to the considered systems. The fault estimator is designed by using the multiple Lyapunov-Krasovskii functional and average dwell-time approach. Sufficient conditions in the form of linear matrix inequalities (LMIs) are developed to ensure the resulting error system is exponentially stable with an optimized H 1 disturbance attenuation level. The gain matrices of the estimator can be easily determined by using the standard optimization toolboxes. Finally, numerical examples and simulation results with the help of real-time systems are given to illustrate the effectiveness and advantages of the obtained results.
