区间Ⅱ型变论域自适应模糊逻辑控制器
Interval type-2 variable universe adaptive fuzzy logic controller
摘要
Abstract
The type-2 fuzzy sets are more robust,and have ability of tackling the uncertainty problems.Based on the merits of type-2 fuzzy sets and variable universe adaptive fuzzy control method,an interval type-2 variable universe adaptive fuzzy logic controller is proposed.The parameters of the interval type-2 membership functions are optimized by particle swarm optimization algorithm to get the most effective interval type-2 variable universe adaptive fuzzy logic controller.Lyapunov method is adopted to verify the stability of the proposed fuzzy logic controller.Finally,the tests of the proposed controller on the Duffing system and 1-dimension 6-scroll chaotic system are performed.Simulation results show that the interval type-2 variable universe adaptive fuzzy logic controller can track the trajectory well and reduce the chattering efficiently,at the same time can keep the control input small compared with variable universe fuzzy logic controller.关键词
