| 摘 要： | 针对一类非线性、快时变性以及模型不确定性问题,设计了一种基于变论域的模糊自适应控制器。利用模糊模型逼近控制系统的非线性部分,以及采用李亚普诺夫方法证明所设计的非线性控制系统的渐进稳定性并推导出自适应律。最后将设计的控制器应用于倒立摆,仿真结果表明跟踪性能良好。

| Abstract: | Adaptive fuzzy controller based on variable universe approach is designed to the question of nonlinear model uncertainties and fast variable time characterizes in this paper.Variable universe fuzzy model are designed to approximate the uncertainty part,then,the Lyapunov stability theory is used to guarantee the closed-loop stability and proved that the asymptotic stability of nonlinear control system,and derive the adaptive rules.Finally,the results of simulation demonstrate the controller achieve excellent tracking performance. |
