摘要
针对传统迭代观测器和迭代学习观测器存在的故障估计精度低,以及非奇异终端滑模容错控制器和非奇异快速终端滑模容错控制器在执行器故障下收敛时间长等问题,提出了一种改进型迭代学习观测器和一种改进型非奇异快速终端滑模容错控制器,并通过Matlab/Simulink仿真实验验证了所提改进型迭代学习观测器和改进型非奇异快速终端滑模容错控制器的有效性.
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.
