| 摘 要： | 本文提出一种基于输出电压微分反馈控制和重复控制的逆变电源波形数字化控制方案.内层的电压微分反馈补偿器可以在离散域任意配置逆变电源极点位置,极大地改善了逆变电源动态性能,外层的重复控制则致力于提高稳态精度.该方案在一台基于DSP TMS320F240控制系统的PWM逆变电源上得到验证,实验结果证明在仅使用输出电压反馈的前提下,该方案能得到高质量的输出波形.

| Abstract: | One digital control scheme,which is based on output voltage differential feedback control and repetitive control,is proposed in this paper.Arbitrary pole assignment can be achieved with the voltage differential feedback compensator inner loop,which can improve the dynamic characteristic of inverter;the repetitive control outer loop improves the steady state performance of inverter.The scheme,which can achieve the same control effectiveness as "state feedback pole assignment plus repetitive control" without current sensor,is proved on a PWM inverter whose control system is based on DSP TMS320F240. |
