Abstract: A novel adaptive fuzzy global fast terminal sliding mode control scheme is proposed.On the condition of parametric uncertainties and disturbance,it provides a new method to resolve the nonlinear uncertainty of system.Compared to the conventional fuzzy terminal sliding mode control,in the proposed scheme,fuzzy logic systems are used to approximate the unknown system functions and switch item.Robust adaptive law is used to reduce the approximation errors,thus the chattering phenomenon is alleviated effective.Stability of the proposed control scheme is proved and the scheme is applied to an inverted pendulum system.Simulation studies show the effectiveness of the proposed method.

Key words: adaptive fuzzy control, global fast terminal sliding mode control, nonlinear system, approximation

摘要: 提出了一种自适应模糊全局快速Terminal滑模控制方法,在参数不确定性和外干扰情况下,为解决系统的非线性不确定性提供了一种新途径。与传统模糊Terminal滑模控制相比,通过采用模糊逻辑系统来逼近未知系统函数和开关项;鲁棒自适应律用来减小逼近误差,从而有效降低抖振;证明了该控制方案的稳定性,并将该方案应用在倒立摆系统中。仿真结果验证了该方案的有效性。
