Nonlinear active disturbance rejection control of motor driven parking system

The motor is the power source of the electric vehicle. which can start quickly and control the output torque accurately by vector control technology. Aiming at the braking problem of the electric parking system of electric vehicles, This paper proposes an active disturbance rejection control technology to drive the motor to achieve parking. To this end, the longitudinal kinematics model of the vehicle on the slope is analyzed, combined with the mathematical model of the motor and the vehicle model, the nonlinear auto-disturbance controller of the electric vehicle electronic parking is designed, and the closed-loop simulation model is built. The simulation results show that the response performance of the active disturbance rejection control system is obviously better than that of PID control. Finally, through experiments, it is verified that the designed control scheme has a good response to the internal and external disturbances in the parking process, and can realize rapid and effective braking during parking.
