This paper considers the problem of robust fault estimation for discrete-time switched system. Firstly, an augmented system is constructed such that the fault as part of the state. Then an unknown input observer (UIO) is employed to estimate the state of the augmented system. Based on the switched Lyapunov function and the generalized Kalman-Yakubovic-Popov (KYP) lemma, a finite-frequency UIO-based...
This paper is concerned with robust filtering problem for discrete-time switched systems in which each subsystem is described by T-S fuzzy models. The switching law is mode-dependent and each subsystem has its own average dwell-time. The premise variables choose the system output. The robust filters are designed such that the augmented system is asymptotically stable, and also guarantee weighted l...
This paper addresses the design of switching rule for robust stability of a class of uncertain switched system with delay. The system to be considered is autonomous and the state delay is time-varying. Using Lyapunov functional approach, restriction on the derivative of time-delay function is not required to design switching rule for the robust stability of switched systems with time-varying delays...
