Passive Control for a Class of Network Control Systems with Time-varying Delays

文章研究了一类变时滞网络控制系统的无源控制问题,首先根据传输时延得到系统的等价动态模型,通过构造观测输出和状态反馈,由耗散下的无源指标得出相应的算式,并利用基于凸多面体的方法来求解变时滞引起的变参数LMI,使闭环系统达到满意的控制要求,仿真结果说明本文方法的有效性。

Passive control of a system with time - varying delays is studied in the paper. First, they get the equivalent model according to the time - delay, and then construct measure output and state feedback. By means of passive index, the correspondent expressions can be obtained. Using the method of parameter - dependent LMI based on convex polyhedron, we get the feasible solutions, making the closed - loop system satisfied with the desired control request. The simulation shows the effectiveness of the method.
