A Novel Inductance Identification Method for Surface-mounted Permanent Magnet Synchronous Motor Used in Electric Bus

S. Zhang, Y. Zhou, X. Yuan


The control strategies of motor driving system determine the driving system’s performance. To evaluate the control performance of different motor control strategies including traditional proportion integration control, deadbeat predictive current control and direct torque control, this study constructs an electric bus model to simulate the motor driving system’s load property. To promote the control performance of deadbeat predictive current control, a novel inductance identification method is proposed. The simulation results indicated that the deadbeat predictive current control shows best performance and the effectiveness of the inductance identification method is verified.
