| 摘 要： | 传统PI控制对具有非线性、大时滞、时变、强耦合等特性的被控对象的控制效果不理想。针对该问题,将模糊PI控制引入到交-交变频同步电机调速系统中,以模糊PI控制器代替传统的PI控制器。阐述了模糊PI控制器的原理以及算法,最后将其应用到12kW交-交变频三相同步电机系统中。实用表明,系统的各项参数指标均优于传统PI控制。

| Abstract: | The PI control method is not perfect to the object which is nonlinear,time-lag,time-variation or strong-coupling system.To solve this problem,fuzzy-PI control method is introduced to the AC/AC inverter speed-regulated system of synchronous motor and the speed-regulator with PI control is replaced by fuzzy controller.This paper represents the principle and algorithm of fuzzy-PI controller,and then the fuzzy PI control method is applied to the 12kW AC/AC variable frequency three phase speed-regulated system of synchronous motor.Experimental results express that all indexes of fuzzy control method are basically better than those of traditional PI control. |
