摘　　要：将网络化控制系统中被控对象的模型推广到切换系统,利用具有时延的输出信号设计了一种新的观测器,对任意切换规则和延迟周期数,该观测器都能实现对被控切换系统的跟踪。最后给出了求解观测器增益的锥补线性化方法,仿真实例说明所提方法的有效性。In this paper, the plant model of networked control systems is generalized to the switching systems,a novel observer is designed by means of the output signals with time-delay. For an arbitrary switching rule and arbitrary time-delay, this observer can track the controlled switching systems. At last, a cone complementarity linearization method is given to solve the gains of the switching observer, and an example is shown the feasibility of the proposed approach.
