模糊PID控制在SVPWM整流器系统中的仿真研究

Simulation Research for Rectifying System with SVPWM Based on Fuzzy PID Control

文章基于模糊控制及其它智能控制理论,与常规PID控制有机结合形成调整系统控制量的模糊PID控制器,对SVPWM整流器进行仿真研究。仿真结果表明这种模糊PID控制器能使系统响应的超调减小,响应时间加快。

Since the real-time control of the rectifiying system with SVPWM which applies to the conventional PID control has delay lag and the non-determination of environment and disturb ances, the paper introduces the simulation research for the rectifier with SVPWM based on the fuzzy PID controller combined with the conventional PID controller according to the fuzzy control and intelligent control theory. This fuzzy controller can regulate the system control-variable and the result indicates that it can dercease the overshoot of the system response and speed up the time of response.
