摘　　要：针对带有网络延时和数据丢包的网络控制系统,建立异步动态模型.用容错控制理论的混合动力系统技术对传感器和驱动器故障进行分析;基于线性矩阵不等式的可行解建立控制器参数表达式;将数据丢包可能性作为衡量网络服务质量的依据,对网络控制系统进行了完整性设计.在Matlab/Simulink环境下开发模拟器并对该系统进行仿真,结果表明,该方法可以提高网络控制系统容错控制的鲁棒性.Asynchronous dynamic model is established to address the network control system with delays and data package dropout in this paper.First,the faults of sensor and drivers are analyzed based on the hybrid dynamic system technology of fault tolerant control theory.Second,based on the feasible solution of linear matrix inequality,the expression of controller parameters is established.Third,the integrity design of the network control system is completed by using the possibility of packet loss as the basis to measure the quality of network service.In the Matlab/Simulink environment,the system is simulated and the simulation results show that the proposed method improves the robustness of fault tolerant control of network control system.
