In this paper, the adaptive fuzzy controller design problem is investigated for a class of switched nonlinear systems in nonstrict feedback form, in which the unknown functions are considered and are approximated. Moreover, the system states are constrained in corresponding compact. By using Barrier Lypunov function method and backstepping technique, the adaptive fuzzy controller is designed such that all the signals in the closed-loop system are bounded, the system output can track the desired signal to small compact, and all the system states satisfy the constraint conditions. Finally, the simulation results show the effectiveness of the proposed method.

非严格反馈形式切换非线性系统的自适应模糊约束控制

本文研究了一类非严格反馈形式的切换非线性系统的自适应模糊控制器设计问题，其中考虑并逼近未知函数。此外，系统状态被约束在相应的紧凑型中。利用 Barrier Lypunov 函数法和反推技术，设计了自适应模糊控制器，使得闭环系统中的所有信号都是有界的，系统输出可以跟踪期望信号到小紧凑，并且所有系统状态都满足约束状况。最后，仿真结果表明了所提出方法的有效性。
