摘　　要：为了增强网络化切换系统适应时延的动态性能,利用Lyapunov稳定性理论,设计了一种切换观测器和相应的切换控制器,给出了对任意切换规则和延迟周期数,都能保证整个闭环网络化切换系统稳定的充分条件.并给出了求解切换观测器增益和切换控制器增益的锥补线性化方法,仿真实例说明了所提方法的有效性.In order to improve the dynamic performance of the networked switching systems due to time-delay, a switching observer and a switching controller are designed by means of the Lyapunov stability theory. A sufficient condition for the stability of the closed-loop networked switching systems is obtained for the arbitrary switching rule and arbitrary time-delay. Finally, a cone complementarity linearization method is also given to solve the gains of the switching obsrver and of the switching controller, with an example showing the efficiency of the proposed approach.
