不确定时滞关联大系统的全局稳定模糊容错控制
Fuzzy fault-tolerant control for global stabilization of uncertain time-delay large-scale systems
摘要
Abstract
The fuzzy fault-tolerant control problem is studied for global stabilization of a class of uncertain nonlinear interconnected large-scale systems with unknown time varying time delays. The unknown delayed input signals of the fuzzy approximator are substituted by the bounded references signals, and as a result, the control design and application are not dependent on the delay assumptions any more, so that the convenience of the controller design and application is greatly improved. The fault-tolerant backstepping control and the adaptive control technique are combined to deal with the errors of the replacement and the approximation. The proposed control scheme can compensate for all of the four types of actor faults efficiently, and global stability of the closed-loop system is guaranteed. Simulation results are provided to show the effectiveness of the control approach.关键词
