摘要
在建立三相PWM整流器dq模型的基础上,提出了一种电压PI控制和基于输入输出线性化电流控制的PWM整流器混合控制策略,来实现整流器的高性能特性,并构建了基于DSP的PWM整流器实验装置,介绍了整流器的硬件和软件设计。实验结果验证了控制策略的有效性,PWM整流器的动态性能较好,直流输出电压稳定,网侧输入电流正弦化,且功率因数接近于1。
Based on the dq model of three-phase PWM rectifier,in order to realize rectifier high-performance features,a hybrid control strategy combined voltage PI control with current control based on input-output linearization for PWM rectifier was presented.PWM rectifier experiment device was constructed based on DSP,and the hardware and software design of rectifier was introduced.Experimental results verify the validity of the control strategy,the dynamic performance of PWM rectifier is good,DC output voltage stability,the current wave of electricity net side is ensured being sinusoidal,and the power factor is approching unity.
