| 摘 要： | 为了克服时延和不确定参数对系统性能的影响,利用Lyapunov稳定性理论,设计了一种新的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。最后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。

| Abstract: | In order to eliminate the effect of time-delay and uncertain parameters for networked switching systems,a switching observer and a switching controller are designed by means of the Lyapunov stability theory.A sufficient condition of the stability for the closed-loop networked switching systems is obtained for arbitrary switching rule and arbitrary time-delay.At last,a cone complementarity linearization method is also given to solve the gains of the switching observer and of the switching controller,an example shows the efficiency of the proposed approach. |
