This paper presents an adaptive fuzzy control scheme for a class of nonstrict‐feedback nonlinear systems with dead zone outputs and prescribed performance. By utilizing the monotonically increasing property of system bounding functions and the Nussbaum function, the design difficulties caused by the nonstrict‐feedback structure and dead zone output are overcome. Combining backstepping technique with prescribed performance algorithm, a feasible adaptive fuzzy controller is designed to guarantee the boundedness of all signals of the closed‐loop system and the prescribed tracking performance of the system. Finally, simulation results are depicted to illustrate the effectiveness of the proposed control approach.

具有死区输出的非严格反馈非线性系统的规定性能自适应模糊控制

针对一类具有死区输出和规定性能的非严格反馈非线性系统，提出了一种自适应模糊控制方案。通过利用系统边界函数和Nussbaum函数的单调递增性质，克服了非严格反馈结构和死区输出所带来的设计难题。将反推技术与规定的性能算法相结合，设计了一种可行的自适应模糊控制器，以保证闭环系统所有信号的有界性和系统规定的跟踪性能。最后，仿真结果被描述以说明所提出的控制方法的有效性。
