摘要
研究具有长时延广义网络控制系统鲁棒H∞控制问题,假定传感器是时间驱动,控制器和执行器是事件驱动,网络时延在2个采样周期之间,有限的外部能量扰动网络化控制系统,利用状态增广的方法,建立离散时变的不确定系统模型,并利用李雅普诺夫理论和线性矩阵不等式描述方法,推导出了动态输出反馈H∞控制律存在的充分条件。以仿真实例说明了该方法的有效性。
To study the robust H∞infinity control for generalized networked control systems with long time delay,it is assumed that the sensors are clock-driver,and controllers and actuators are event-driver in two sampling periods and limited energy of the external disturbance.The augmented state is used to establish uncertain system model of discrete time-varying,and by using Lyapunov function and linear matrix inequalities,the sufficient conditions for dynamic output H∞infinity feedback control are found out.A simulation example shows the effectiveness of the method.
