摘要/Abstract

摘要： 针对一类同时具有介质访问约束和随机时延的网络化控制系统,研究了其中的动态输出反馈控制设计问题. 考虑到介质访问约束和随机时延的影响,将系统建模为一类具有参数不确定性的马尔可夫跳变系统,基于李雅普诺夫稳定性理论和LMI技术推导出系统稳定的充分条件,并且设计了相应的动态输出反馈控制器,使得闭环系统鲁棒稳定并具有给定的H_∞性能,最后通过仿真算例证明了所提出方法是有效的.

Abstract: The dynamic output feedback control problem is investigated for a class of random-delay networked control systems with medium access constraints. Considering the effects of medium access constraints and random delay, the systems are modelled as a class of Markov jump systems with parameter uncertainty. Based on Lyapunov stability theory and LMI technology, the sufficient conditions for stochastic stability are derived, and the corresponding dynamic output feedback controller is designed to make the closed-loop system robust stability with a given H-infinity performance. Finally, an illustrative example is provided to demonstrate the effectiveness of the proposed method.

Key words: networked control system, medium access constraints, random time-delay, dynamic output feedback
