摘　　要：笔者研究了一类网络控制系统(NCSs)的模型参考输出跟踪问题。基于Lyapunov稳定性理论和线性矩阵不等式(LMI)方法,推出了该网络控制系统的稳定性和控制器设计的充分条件,并通过MATLAB求出该控制器的解。对于能量有界的外界扰动输入信号,设计的控制器能够保证随机网络控制系统的H∞性能指标小于一定值γ。仿真实例证实了该设计方法的有效性。This paper is concerned with the model reference output tracking problem for networked control system.Attention is focused on the design of controller,which guarantee that the stability of system and a prespecified H∞performanceγfor the networked control system with respect to all energy-bounded input signals.Sufficient conditions are proposed in terms of Lyapunov stability theory and linear matrix inequality(LMI)method,and the solution of the controller is obtained by MATLAB.A numerical example illustrates the effectiveness of the proposed H∞ output tracking design scheme.
