In this paper, an adaptive fuzzy control scheme for strict-feedback nonlinear system with finite-time prescribed performance and actuator fault is studied. First, we consider a prescribed performance function that enables the tracking error to converge within a preset interval in a finite time. Subsequently, the fuzzy logic system and dynamic surface control technology are embedded in the backstepping design process, and the purpose of the dynamic surface control technique is to settle the problem of computational explosion when processing the backstepping design. The fuzzy logic system is used to approximate the unknown functions that appear in the system. Finally, a new controller is designed in combination with an updated law which ensures that all the signals in the closed-loop is bounded. Two simulation examples are taken to illustrate the feasibility of the presented control scheme.

具有执行器故障的严格反馈非线性系统的规定性能动态曲面模糊控制

在本文中，研究了具有有限时间规定性能和执行器故障的严格反馈非线性系统的自适应模糊控制方案。首先，我们考虑一个规定的性能函数，使跟踪误差能够在有限时间内收敛到预设区间内。随后，将模糊逻辑系统和动态曲面控制技术嵌入到反推设计过程中，动态曲面控制技术的目的是解决反推设计过程中的计算爆炸问题。模糊逻辑系统用于逼近系统中出现的未知函数。最后，结合更新的法则设计了一个新的控制器，该法则确保闭环中的所有信号都是有界的。
