不确定时延广义网络控制系统的保性能控制

Guaranteed Cost Control for the Singular Networked Control System with Uncertain Time-Delay

研究了正则且无脉冲的广义网络控制系统的保性能控制问题.针对传感器是时钟驱动,控制器和执行器是事件驱动,且网络的不确定时延小于一个采样周期的广义网络控制系统,利用李亚普诺夫理论和线性矩阵不等式,推导出系统状态反馈保性能控制律存在的充分条件,并给出了设计方法.最后通过数值仿真,给出了含有不确定性时延的广义网络控制系统的状态反馈保性能控制律,说明了该方法的有效性.

The problem of guaranteed cost control for the regular and impulse-free singular networked control system was studied. For the singular networked control system with clock- driven sensor, event-driven controller and actuator, and the uncertain time-delay not more than one sampling period, the sufficient condition of the existence of guaranteed cost control law for state feedback was derived through Lyapunov theory and linear matrix inequality, and the guaranteed cost control law design method for state feedback was also proposed. Finally, the state feedback guaranteed cost control law for singular networked control system with uncertain timedelay is demonstrated by a simulation example, thus the proposed approach is valid.
