基于多分支采样的低速无传感器控制采样延迟误差补偿

This article proposes a sampling-delay error compensation for high-frequency (HF) injection sensorless control based on multiple-branch sampling at zero and low-speed domains. In existing single-current sensor sampling schemes, sampling-delay errors are inherently present due to two samplings occurring at different moments. These errors deteriorate the accuracy of HF current reconstruction and con...
