具有有界输入的网络控制系统时延独立稳定性

Delay-indenpendent Stability of Networked Control Systems with Bounded Input and Dynamic Output Feedback

基于有界时延、无数据包丢失、传感器时钟驱动、执行器事件驱动,文章提出了用一个特定的实值函数来调节动态输出反馈控制器的输出以确保控制对象输入有界的方法,建立了具有分布时延、有界输入、动态输出反馈网络控制系统的非线性数学模型。用李雅普诺夫第二方法和线性矩阵不等式描述分析了系统的渐近稳定性,并推导出与时延无关的系统渐近稳定的充分条件。最后MATLAB仿真算例说明:稳定判据是可行的,有界输入的控制方法是有效的。

Based on bounded time delay, no data packet dropout, clock - driven sensors and event driven the controller and actuators, this paper presented the method that a special real function is used to adjust output of the controller to guarantee Dounded input for controlled plant, and developed the non linear mathematic model of networked control systems with distributed time delay, bounded input and dynamic output feedback. The asymptotic stability of the system was analyzed using Lyapunov second method and linear matrix inequalities description, and the sufficient condition of delay - independent asymptotic stability of the system was derived. An MATLAB simulation example shows that the stability criterion is feasible and the control method bounded input is valid.
