摘　　要：研究一种对象的输出信号通过网络反馈到单控制器,控制器的输出信号通过网络传输到执行器的多输入多输出控制系统。给出了该类网络控制系统的结构图,针对线性时不变的被控对象,建立了系统的综合数学模型,采用Lyapunov分析了其稳定性,推导出时滞独立的稳定条件。并通过数值算例验证了其可行性。A kind of MIMO networked control system,in which each output signal of object controlled is obtained by an independent sensor and then sent to a single controller through a network,and also each output signal of the controller is sent to an independent actuator through the network,is studied in this paper.The figure of its structure is given,and its mathematic model is set up.Based on the Lyapunov theory,the delay-independence condition subject to the stability of the MIMO networked control system is derived.A numerical example given testifies that the method presented in this paper is feasible.
