【摘要】 针对多输入多输出(MIMO)网络化控制系统,分析了控制器的不同工作方式对网络时延的影响,建立了传感器节点为时间驱动、控制器节点和执行器节点为事件驱动时的离散时间数学模型,设计了满足给定离散性能指标的随机最优状态控制器,该控制器能使网络化控制系统均方指数稳定。仿真结果表明了本方法的有效性。更多还原

【Abstract】 Considering the multi-input and multi-output networked control systems,Influences of the controller’s driven style on the network-induced delay are discussed.The discrete time model is derived which the sensor nodes are clock-driven,the controller node and the actuator nodes are event-driven.A stochastic optimal controller is designed to satisfy the given dis-crete performance index,which can also make the networked control systems exponentially mean square stable.A simulation experiment illustrates the effectiveness of the presented theory.更多还原
