摘要
针对多包传输网络控制系统的鲁棒性,提出实现H∞性能时的控制器设计方法.根据特性将系统建模为切换系统,利用分段Lyapunov函数对系统的稳定性及H∞性能进行论证,并以线性矩阵不等式(LMI)形式给出H∞控制器需满足的条件.通过对实例H∞控制器的实现,来证明结果的有效性、正确性.
To analyze the robustness of NCS （networked control system） with multi-packet transmission, a method of controller designing is proposed to realize the system H∞performance. Based on its character, system is modeled as switching system. Piecewise Lyapunov function is utilized to demonstrate the stability and H^performance of the system. Thert the condition is presented which the controller of H∞should be satisfied via LMI（linear matrix inequality）, An example is provided to illustrate the validity of method by realizing the controller of H∞.
