Abstract

Abstract: The concept of passivity is extended to T-S fuzzy generalized switched systems， and then the passivity problem for asynchronous situation between a class of subsystem switching and observer-based controller switching is studied. Firstly， by using piecewise Lyapunov function and model dependent average dwell time， the sub-systems with excess passivity can compensate for the sub-system with insufficient passivity， so as to ensure the overall passivity of the switched system. Afterwards， the sufficient conditions for globally uniformly exponential stability and strictly exponential passivity of T-S fuzzy generalized switched systems with time delay are obtained by using the linear matrix inequality method， and the corresponding observers and controllers are designed. Finally， numerical examples are provided to validate the effectiveness of the method.

Key words: observer; time delay; asynchronous controller; passivity; generalized switched systems
