CVCF逆變器波形控制技術研究

摘要：本文提出了一種將重復控制與引入積分控制的極點配置相結合的混合型控制方案。其中重復控制改善系統的穩態性能，極點配置改善系統的動態特性。兩種控制方式互為補充，可以同時實現高品質的動態響應和高質量的輸出電壓波形。 敘詞：CVCF逆變器；重復控制；積分控制；極點配置 Abstract：A hybrid control structure incorporating repetitive control and pole-assignment control with integral control is proposed. Repetitive controller is adapted to improve the steady-state performance; Pole-assignment controller can greatly improve the dynamics of the PWM inverter. Combination of these two complementary strategies gives excellent dynamic response as well as high quality voltage waveform.
