摘　　要：近年来，模糊逻辑或模糊集理论在电力电子技术和微机控制技术的应用领域得到了广泛的研 究．在分析常规ＰＩＤ、模糊控制和复合模糊控制等几种方案的基础上，提出了一种基于参数自调整模 糊控制器的交流闭环调速系统的设计方法，详细讨论了在参数自调整模糊控制器中使用的模糊控制 表和模糊调整表的设计步骤．仿真和实验结果证明了该方案能克服传统的交流调速系统中常规控制 不能适应工况变化的弊端，具有优良的控制特性和很强的鲁棒性，可满足高精度调速系统的要求，证 实了参数自调整模糊控制器在交流闭环调速系统中应用的必要性和有效性．Recently, fuzzy logic or fuzzy set theory has received attention of a number researchers in the area of power electronic and microcomputer control. This. paper presents a design method of AC colsed--loop drive system based on the fuzzy controller with self- adjusting parameters. After the analysis of features of PID control, fuzzy control, and compound fop controller has been made. The design scheme of the fuzzy control table and fuzzy adjustable table are also discussed for the use of the fuzzy controller with self-adjusting parameters. The simulation results and experiment results prove that the method can overcome the defect of conditional controller not changing with random disturbance parameters, has good control characteristic and strong robustness, satisfies the demands or high accuracy drive system, demonstrated the necessity and validity of application of the fuzzy controller with self-adjusting parameters to AC closed-loop drive system.
