Speed Active Disturbance Rejection Control of Permanent Magnet Synchronous Wheel Hub Motor for Hybrid Electric Vehicles

Aiming at the problem that the speed tracking accuracy of Permanent Magnet Synchronous Wheel Hub Motor (PMSWHM) for hybrid electric vehicles is not high under complex disturbance conditions, the model of PMSWHM speed Active Disturbance Rejection Control (ADRC) system is established and the ADRC parameters are set. Under the condition of load torque disturbance and model mismatch disturbance, the rotational response of PMSWHM under ADRC is studied, and it is compared with the simulation results of PID controller with optimized parameters. The results show that the ADRC has the unique advantage of improving the speed response and reducing the speed overshoot of PMSWHM.
