| 摘 要： | 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。

| Abstract: | Consider a MIMO networked control system with uncertainty time varying sensors and controller event-driven actuators,and network-induced time delays that are less than the sampling period.Sensors that fail to transmit data are assumed to be temporarily invalid.The networked control system with sensor faults was modeled as a system with system uncertainties.The sufficient condition for stability was found using the Lyapunov method.Separate approaches are derived for the controller and the observer based on solutions of the linear matrix inequalities.The resulting fault-tolerant MIMO networked control system is found to effectively handle sensor failure and develop. |
