基于遗传算法的模糊系统优化设计方法*

提出一种带有混合变长编码和模糊变异算子的新型模糊遗传算法，并将其应用到模糊系统的优化设计中．仿真结果表明，这种方法具有即使系统缺乏任何先验知识，也能通过评价学习、遗传优化获得满足系统动态性能的优化控制规则的特点.

An Optimal Design Approach for Fuzzy System Based on Genetic Algorithm

This paper proposes a novel fuzzy genetic algorithm,which has the characteristics of hybrid length-varying cod-ing scheme,separates optimal ability and fuzzy mutation operator.The fuzzy genetic algorithm is applied to the optimal design of fuzzy systems.Simulation results performed on the inverted pendulum control show that proposed desiign scheme can acquire the satisfied dynamic performance by learning and genetic optimization even for lack of any prior knowledge.
