Motor Controller Design for Hybrid Electric Vehicle Based on Vector Control

To meet the demands of fast torque response on HEV,the vector control algorithm based on rotor magnetic orientation is concerned and the simulation model is established.Simulation results confirm that the proposed algorithm can obtain good dynamic tracking ability.Then a modular design for hardware and software of the controller is presented to construct the motor control platform.The series of anti-jamming and vibration isolation measurements are taken especially to ensure the controller can adapt to the working environment of HEV.The motor test bench is set up for experiments and the results show that the designed driving system has fast torque response ability,wide speed adjusting range and high comprehensive efficiency.
