摘　　要：基于一类sum-product模糊推理算子、重心解模糊化法和单点输出的典型模糊控制器的解析结构推导,深入分析了输入隶属函数对模糊控制系统性能的影响,提出了隶属函数的系统化设计方法。并在此基础上,设计了一种具有等差间距因子的三角形隶属函数并推导了其模糊控制器的解析结构,仿真结果证明了该设计的有效性。Based on the analytical structure of a typical fuzzy controller with sum-product fuzzy operator,central-defuzzification method and single-point output,the influence of membership function on fuzzy control system is analyzed in detail,and the systematic design method of membership function is obtained.Based on these results,a kind of triangle membership function with difference-interval factor is designed and its analytical structure is derived.Finally,simulation is given to manifest the effectiveness.
