基于自适应遗传算法的模糊控制器应用研究

Applied Research of Fuzzy Logic Controller Based on Adaptive Genetic Algorithm

传统模糊控制器的设计主要依赖专家经验,存在较强的主观性和随意性,使得控制精度不高。为此,利用自适应遗传算法,优化设计了模糊控制器,并将其应用到三相异步电机的转差频率矢量调速系统中。仿真结果表明,控制效果好于PI控制。

As the traditional design methods of fuzzy logic controller rely mainly on the experience of experts and exist both arbitrariness and subjectivity which make the control accuracy low, the optimization design of the fuzzy controller was carried out with the adaptive genetic algorithm, and applied to the slip frequency vector control system of a three-phase induction motor. The simulation results show that the control effect of the optimized fuzzy controller is better than that of the traditional fuzzy controller.
