| 摘 要： | 针对电能质量中的电压不平衡问题,提出了一种新的改进无差拍控制方法.该方法在传统无差拍控制的基础上引入了参考电流观测器和状态观测器,将当前的输…电流和正弦信号的加权平均作为下一控制剧期的甘标量,以提高对负载参数变化的鲁棒性.仿真和实验结果表明,该方法可有效补偿不平衡电压,而且动态响心很快.

| Abstract: | A novel control method i.e.improved dead-beat control method is proposed to solve the voltage unbalance issue.The proposed method introduces the reference-current-observer and state observer on the basis of traditional deadbeat.In this novel control method the weighted average of the sinusoidal reference signal and the output current signal is chosen as the target value of the next sampling instant to improve the robustness to the load parameters change.The simulative and experimental results show that this... |
