摘要: 引入了一种新的无源不等式到T-S模糊广义切换系统中,进而研究了一类子系统切换与基于观测器的控制器切换存在不同步情况的系统无源性问题.首先,运用分段李雅普诺夫函数和模型依赖平均驻留时间的方法,通过无源性过剩的子系统来弥补无源性不足的子系统,从而确保切换系统的整体无源性;然后,利用线性矩阵不等式的方法得到时滞T-S模糊广义切换系统的全局一致指数稳定和严格指数无源的充分条件,并据此设计出相应的观测器和控制器,最后给出数值算例证明该方法的有效性.

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
