Adaptive fuzzy fault-tolerant control problem for a class of uncertain switched stochastic nonlinear systems with time-varying asymmetric output constraints is addressed in this study. Under the action of well-designed asymmetric nonlinear mapping, fuzzy control technology, and backstepping recursive design scheme; the actuator faults of both loss of effectiveness and lock-in-place are considered to develop the adaptive fuzzy controller. The boundedness of all signals as well as the convergence of the output tracking error of the closed-loop plant to an arbitrary small neighborhood about zero are guaranteed by the developed fuzzy adaptive control strategy, and the time-varying output constraints are not violated. A simulation example is worked out to demonstrate the validity of the proposed control scheme.

具有时变输出约束的不确定非线性切换随机系统的自适应模糊容错控制

本研究解决了一类具有时变非对称输出约束的不确定切换随机非线性系统的自适应模糊容错控制问题。在精心设计的非对称非线性映射、模糊控制技术和反推递归设计方案的作用下；考虑执行器失效和锁定到位的故障来开发自适应模糊控制器。所开发的模糊自适应控制策略保证了所有信号的有界性以及闭环设备的输出跟踪误差收敛到零附近的任意小邻域，并且不违反时变输出约束。一个仿真例子被制定来证明所提出的控制方案的有效性。
