Research on sensorless vector control system for hub motor based on EKF
To solve the problems of weak anti-interference ability and slow system response speed of vehicle mounted hub motors,a sensorless vector control model for vehicle mounted hub motors,was built a control system based on Extended Kalman Filter(EKF)algorithm was designed,and finally was verified through simulation us MATLAB/Simulink software.The simulation results showed that the vehicle mounted PMSM sensorless vector control system based on the EKF algorithm could maximize the improvement of the response speed,anti-interference ability,and operational performance of the vehicle mounted hub motor,enhance the robustness of the system,meet the dynamic control requirements of the vehicle mounted hub motor within the global operating range of the vehicle,and provide theoretical support for expanding the range of vehicle dynamic control.
