资料介绍

为使逆变电路具有更高的控制精度和更强的带负载及抗负载扰动能力,研究采用闭环控制的单相逆变电路。设计了电压单环和电压电流双环两种控制方案的控制器,并采用极点配置法确定相关参数。利用Simulink仿真模型对比分析了在非线性负载和突变负载情况下单环与双环控制的逆变输出电压和电流的波形。结果表明:双环控制下单相逆变电路电压变化率小、谐波含量少,具有更好的带负载及抗负载扰动能力。

For the inverter circuit's higher control precision and stronger loading and anti load disturbance capacity,the closed-loop control of single-phase inverter is ing two control schemes of voltage single-loop and voltage current double-loop,the controllers of these two schemes are designed and the corresponding parameters are determined by the pole assignment simulation models of single-loop and double-loop control system with single-phase inverter circuit are built in the Simulink simulation waveforms of the output voltage and current of the single-loop and double-loop control under the condition of nonlinear load and mutation load are compared and simulation results show that under the double-loop control...
