摘要:本文提出了一種自適應重復控制方案并將其應用于脈寬調制逆變器,這種控制方法可以自適應地消除由交流源中未知的周期負載擾動而引起的周期性失真。仿真和實驗的結果都證明了基于DSP的自適應重復控制器即使在大的負載擾動下也能獲得良好的動態響應和低的THD.

Abstract:An adaptive repetitive control scheme is presented and applied to the control of a pulsewidth-modulated (PWM) inverter used in a high-performance ac power supply. The proposed control scheme can adaptively eliminate periodic distortions caused by unknown periodic load disturbances in an ac power supply.
