摘要 为了提高逆变器的稳定性和供电质量,文中介绍了一种基于极点配置的逆变器瞬时电压电流PI控制器的设计方法,建立了系统模型,比较分析了基于电感电流反馈控制和基于电容电流反馈控制技术。仿真结果表明,基于电感电流电压双环控制技术具有较好的输出特性。 In this paper, the design method of inverter instantaneous voltage-current PI controller based on pole-assignment is proposed and mathematical models of a single-phase PWM inverter are established. The instantaneous capacitor-current feedback loop control strategy is compared with the instantaneous inductance-current feedback loop control strategy. Simulation results indicate that the instantaneous capacitor-current and voltage dual-loop feedback control strategy has high performance of output voltage.
