摘　　要：在基于多包传输的网络控制系统中,传感器采用时间驱动,控制器和执行器采用事件驱动。假定传输时延可以忽略,则整个网络控制系统可以描述为一个具有N个事件的异步动态系统。该文针对受控对象状态均可测,控制律采用输出反馈的情况,利用双线性矩阵不等式方法,讨论了网络控制系统指数稳定的问题,并给出了稳定性的充分条件,最后通过仿真实验加以验证。Considering the networked control system based on the multiple -packet transmission, the sensor node is time - driven while sampling at a fixed period, the controller and actuator are event - driven. Assuming the transfer delay to be ignored, the networked control system is an asynchronous dynamic system with N- events. The method of the bilinear matrix inequality is used to discuss the system＇s exponential stability with the output feedback control when the controlled system state is acquirable. The simulation experiment shows the effictiveness and feasibility of our proposed approach.
