CVCF逆變器波形控制技術(shù)研究

摘要：本文提出了一種將重復(fù)控制與引入積分控制的極點(diǎn)配置相結(jié)合的混合型控制方案。其中重復(fù)控制改善系統(tǒng)的穩(wěn)態(tài)性能，極點(diǎn)配置改善系統(tǒng)的動(dòng)態(tài)特性。兩種控制方式互為補(bǔ)充，可以同時(shí)實(shí)現(xiàn)高品質(zhì)的動(dòng)態(tài)響應(yīng)和高質(zhì)量的輸出電壓波形。 敘詞：CVCF逆變器；重復(fù)控制；積分控制；極點(diǎn)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.
