摘要
针对网络控制系统中存在的不确定时延,在传感器采用时间驱动,执行器与控制器采用事件驱动、时延小于一个采样周期的条件下,将网络控制系统建模为一类具有不确定性的线性离散系统并且其标称模型可控。围绕该标称模型,利用Lyapunov方法,基于相应的LMI可行解,给出网络控制系统保性能控制律的设计方法。通过仿真证明了该方法的有效性。
Considering the uncertain delay of the networked control system, the sensor node is time-driven, the executor and the controller are event-driven,the networked control system is modeled as an uncertain discrete linear system under the condition that the transfer delay is less than one sampling period. Around the nominal model stable, the control algorithm is proposed based on the Lyapunov function approach and the feasible solution of the linear matrix inequalities. The validity of the method is verified in the simulation.
