针对被控对象为具有不确定因素的多输入多输出网络控制系统,设传感器与控制器均为时间驱动,执行器为事件驱动,网络诱导时延小于采样周期,将未能成功传输数据的传感器节点视为暂时失效,把具有传感器故障的网络控制系统建模为一类带有不确定因素的离散模型,借助Lyapunov定理给出了系统渐近稳定的充分条件,基于LMI方法得出观测器和控制器的分离设计方法,实现了MIMO网络控制系统的容错控制。 Aiming at the multi-input and multi-output networked control system with uncertainties, the sensors and controllers are time-driven, the actuators are event-driven, the network-induced delay is less than the sampling period, and the sensors that fail to transmit data successfully The node is considered as a temporary failure. The networked control system with sensor failure is modeled as a discrete model with uncertain factors. The sufficient conditions for the asymptotic stability of the system are given by Lyapunov theorem. The observer and Controller separation design method to achieve fault-tolerant control of MIMO network control system.
