摘要
三相PWM整流器因其数学模型难以精准确定,且容易受到外部干扰,常规的PI算法控制效果不佳、动态响应速度慢、鲁棒性差.本文在传统PI控制的基础上加入模糊控制算法,将模糊控制与PI控制相结合,有效提高了系统的动态性能.最后通过Simulink实现模糊PI控制算法,并与传统PI控制进行比较,实验结果表明,模糊PI控制算法具有更好的动态特性和更强的抗干扰能力.
Three-phase PWM rectifiers are difficult to accurately determine because of their mathematical models and are susceptible to external interference.Conventional PI control algorithms have poor control effects,slow dynamic response,and poor robustness.This article adds fuzzy control algorithms on the basis of traditional PI control,and combines fuzzy control with PI control,which effectively improves the dynamic performance of the system.Finally,the fuzzy PI control algorithm is realized by Simulink and compared with the traditional PI control.The comparison of the two sets of experimental data shows that the fuzzy PI control algorithm has better dynamic characteristics and stronger anti-interference ability.
