摘　　要：文章提出了一种结合变环宽滞环控制和重复控制的DPM逆变器复合控制方案,利用滞环控制可确保系统具有良好的动态性能,采用重复控制能提高系统在周期性负载扰动下的稳态精度。在此基础上,提出了一种变环宽的滞环控制策略,提高了滞环控制的稳定性。设计了一台400Hz、1kV·A数字控制DPM逆变器,实验结果证实了本控制方案的有效性和可行性。A novel hybrid control scheme based on the digital variable-band hysteresis control and the repetitive control is proposed for the discrete pulse modulation(DPM)inverter.The good dynamic response of the DPM inverter is realized by the digital hysteresis con trol.and the steady state control performance of the inverter at rectifier load is improved significantly by the repetitive control.Further- more,the variable band of hysteresis control is presented to increase the stability of the control system.The 400...
