针对严重非线性静止同步补偿器模糊逻辑控制隶属函数的参数和模糊控制规则调整困难的问题,根据微遗传算法,并利用模糊系统的逼近能力,提出了一种模糊控制综合优化设计方法。选择模糊控制器的输入/输出观测信号,应用MATLAB中的模糊控制工具箱快速地获得初始的模糊控制规则,再采用微遗传算法优化其隶属函数参数和模糊控制规则,并给出了模糊控制规则优化后的结果。对带有一个静止同步补偿器的四机电力系统,在三种不同的负荷和三种不同的控制方式下进行仿真实验,结果表明：在宽负荷变化范围内,该控制器的追踪控制能力和鲁棒性等比常规的超前滞后控制、未优化模糊控制都优越。

Aiming at membership function parameters and control rules of fuzzy logic controller (FLC) are difficult to tune for serious nonlinear static compensator (STATCOM), an integrated optimal design of fuzzy logic controller is proposed according to principles of micro-genetic algorithm (micro-GA) and approximation capability of fuzzy system. Observed signals are firstly collected to input and output signals of FLC in this method, and original FLX rules are fast obtained by fuzzy toolbox of MATLAB. Membership functions and control rules are optimized by micro-GA, and the results of optimal FLC are ...
