Adaptive Decentralized Fault-tolerant Control for Uncertain Nonlinear Time-delay Large Scale Systems
摘要
Abstract
In this paper, a delay replacement based adaptive decentralized fault-tolerant control method is proposed for a class of uncertain nonlinear time-delay large-scale systems. With fuzzy logic systems as approximators, a novel delay replacement technique is proposed to deal with the unknown delayed non-linear interconnection functions, and adaptive technique is com-bined to deal with the errors of replacement and approximation. Compared with the existing results, all of the four types of actu-ator faults can be compensated for online, the controller design is no longer depended on the assumptions of the time-delays, and the globally uniformly ultimately boundedness of the closed-loop system is guaranteed. Simulation results are provided to show the effectiveness of the control approach.关键词
