Satisfactory Fault-tolerant Control with Time-delay Memory for Nonlinear Time-delay Systems

针对一类基于T-S模糊模型描述的非线性时滞系统,研究在一般执行器故障模式下的含时滞记忆的鲁棒H∞容错控制器设计问题。针对任意连续型执行器故障模式。

The problem of robust reliable control for nonlinear time-delayed system against actuator failures based on T-S models with H∞ constraint is investigated. For continuous actuator failures of nonlinear time-delayed system, the distributing compensate principle is adopted to design the state-feedback controller with time-delay memory. The stabilization criteria for nonlinear time-delay described by fuzzy T-S model are proposed, and then a robust H∞ tolerant controller is design against actuator failures to guarantee the closed-loop system dynamic and stable performance. The proposed method not only ensure the stability of the close-loop system against actuator fail- ures, but also improve the resistibility for outside disturbance . Finally, simulation example shows the validity and effectiveness of the proposed method.
