摘要

在双闭环控制的单相逆变电源中引入PR调节器作为控制器,以实现对输出波形的无静差跟踪。通过Matlab软件对采用PR双闭环控制策略下的SPWM单相逆变系统进行建模仿真,分析不同比例系数和积分系数情况下的输出波形扰动和谐波抑制情况。实验结果表明,双闭环控制的PR调节器具有良好的跟踪效果和调控特性,降低了输出正弦波的谐波分量,抑制了波形的扰动,提高了系统的稳定性能和逆变输出正弦波形的质量。
        The PR regulator is used as a controller in the single-phase inverter system based on double closed-loop control to realize the output waveform tracking without static error. The SPWM single-phase inverter system based on the double closedloop PR control strategy is modeled and simulated by means of the Matlab software to analyze the disturbance and harmonic suppression situations of output waveforms at different proportion coefficients and integral coefficients. The experimental results show that the PR regulator controlled by the double closed-loop has a good tracking effect and perfect regulation characteristic,can reduce the harmonic components of the output sine waves,inhibit the waveform disturbance,and improve the stability of the system and the quality of inverter output′s sine wave.
