时滞不确定系统的有记忆鲁棒容错控制器设计

Robust fault-tolerant memory controller design of uncertain system with time-delay

为解决线性时滞不确定系统的鲁棒容错控制问题,基于Lyapunov理论,证明系统在不确定性存在的情况下,采用一种有记忆的状态反馈控制律时,对于传感器故障具有完整性,并且运用MATLAB的LMI工具箱求解控制器参数.仿真结果表明该方法的有效性.

This paper deals with robust fault-tolerant control for uncertain linear systems with time-delay.On the basis of Lyapunov theory,a controller based on a kind of memory feed-back control law can keep the uncertainty system's integrity against the sensor failures,and make use of the LMI toolbox in MATLAB,so we can get the parameters of the controller.The simulation results are given to demonstrate the effectiveness of the proposed method.
