摘要
采用事件触发控制策略研究了离散时间线性时延系统的稳定性问题.首先,对于一类离散时间线性时延系统,提出一种新的事件触发控制算法,不同于以往大量的结果,该算法在当测量误差超过了由控制系统状态和系统演化时间决定的动态阈值时,控制器才会更新;其次,给出了系统全局渐近稳定的充分条件,并排除了类Zeno现象;最后,通过MATLAB仿真验证了所提出方法的有效性.
Abstract
The event-triggered control of discrete-time linear time-delay systems are studied.Firstly,for a class of discrete-time linear time-delay systems,a new event-triggered control algorithm is proposed.The controller will be updated only when the measurement error ex-ceeds the dynamic threshold determined by the control system state and system evolution time.Secondly,the sufficient conditions for the global asymptotic stability of the system are given,and the Zeno-like phenomenon is excluded.Finally,the effectiveness of the proposed method is verified by MATLAB simulation.
