本文提出了一种针对单相逆变器的新型二自由度无差拍控制。传统的无差拍系统由于采用高增益反馈控制器，稳定性鲁棒性太差。另一方面，所提出的控制器可以保证多速率前馈控制器的无差拍命令响应以及具有合理增益的反馈控制器保证的稳定性鲁棒性。尽管单速率系统不能保证任意参考信号的零跟踪误差，但所提出的多速率控制可以在每个采样点实现完美跟踪。此外，引入死区时间补偿以减少电压误差。最后，进行了仿真和实验，展示了该方法的优点。
In this paper, novel two-degree-of-freedom deadbeat control is proposed for a single-phase inverter. The conventional deadbeat system had too poor stability robustness because of the high-gain feedback controller. On the other hand, the proposed controller can assure the deadbeat command response by the multirate feedforward controller as well as the stability robustness which is guaranteed by the feedback controller with reasonable gain. Although singlerate systems could not guarantee zero tracking error for arbitrary reference signals, the proposed multirate control can achieve perfect tracking at every sampling point. Moreover, the dead-time compensation is introduced to reduce the voltage error. Finally, the simulations and experiments are performed to show the advantages of the proposed method.
