摘要： 针对一类多输入多输出网络控制系统，将数据包丢失视为系统发生执行器或传感器故障，并用最近一次的采样数据代替本周期未能成功传输的数据，对系统进行容错控制器的设计。首先以控制量丢失为例，基于Lyapunov稳定性理论，推导出了使系统稳定的条件，然后推广到检测量丢失的情况。最后通过仿真示例验证了文中方法的有效性，并对仿真结果进行了分析。

Abstract: Considering a class of multiple-input-multiple-output networked control systems，data packet dropout is treated as failures of actuators or sensors of the systems，the data that failed to transfer in this period are replaced by last sample data，and the fault-tolerant controller is designed for the systems.Firstly，based on Lyapunov stability theory，the stability condition is given for control input dropout.And then the condition is generalized to the systems with measurement dropout.Finally，an illustrative example is given to demonstrate the effectiveness of the proposed method，and the result of the example is analyzed.
Key words: networked control system, fault-tolerant, discrete, controller
