Abstract
This article focuses on a commutation error auto-compensation method for a position sensorless brushless DC motor, which is implemented via DC-link current reconstruction. First, the correlation between commutation error and DC-link current is analyzed. Based on the correlation, a reconstruction circuit is designed to divide the DC-link current into two independent currents, which are reconstructed to indicate commutation error. Then, the DC component of the reconstructed current signal, being positively correlated with the commutation error, is obtained using a low pass filter. It is utilized as the feedback quantity for a closed-loop compensator, which generates and automatically regulates the required compensation angle for the commutation error based on a proportional-integral (PI) algorithm. Finally, the proposed method is verified on a magnetically suspended control moment gyro prototype.
