| 摘 要： | 在双环控制中,为了获得更好的控制效果,逆变器要实现状态反馈解耦。文章在状态反馈解耦的基础上,首先建立了SPWM数学模型,接着对提出的两种控制方案进行了比较,通过分析指令传函的动态跟踪性能和扰动传函的扰动抑制能力,选择了负载电流解耦的电感电流反馈,它是控制效果较好的一种方案,最后对所选的控制方案进行了系统仿真,结果表明输出电压波形质量高,动态响应好,扰动抑制能力强。

| Abstract: | In double-loop control system,in order to obtain better control effect,the inverter must achieve the state feedback decoupling.In this paper,based on state feedback decoupling,the SPWM mathematical model was established,and then the two proposed control schemes are compared,by analyzing the command transfer function of the dynamic track-ing performance and disturbance rejection transfer function of the disturbance,the load current decoupling of the inductor current feedback control is selected as a better scheme.Finally,the simulation results of the selected control scheme show that the output voltage has high-quality waveform,good dynamic response and disturbance rejection ability. |
