执行器乘性故障下容错控制策略研究
Research on fault-tolerant control strategy under actuator multiplication failure
摘要
Abstract
Aiming at the problem of low fault estimation accuracy of traditional iterative observers and iterative learning observers,as well as the long convergence time of nonsingular terminal sliding mode fault-tolerant controllers and nonsingular fast terminal sliding mode fault-tolerant controllers under actuator faults,an improved iterative learning observer and an improved nonsingular fast terminal sliding mode fault-tolerant controller were proposed.The effectiveness of the proposed improved iterative learning observer and improved nonsingular fast terminal sliding mode fault-tolerant controller was verified through Matlab/Simulink simulation experiments.关键词
