Summary:A simple, effective method to realize the integrated control of motoring and regenerative braking of brushless DC motor is proposed in this paper. This method can automatically switch between the two states of motoring and regenerative braking according to the change of load without a braking command and current discontinuity, and can realize steady speed control. For the convenience of analysis, first, the model of the brushless DC motor and the methods of the existing motoring and regenerative braking are briefly explained. Then, the working principle of the proposed method under the two states of motoring and regenerative braking is analyzed. Finally, the effectiveness of the proposed method is verified by experiments.
