Abstract:

According to the transmission structure of system the hybrid electric vehicle with split dual-rotor motor and by taking into consideration the mechanical coupling between the primary motor and the secondary motor,the mathematical model of the split dual-rotor motor is established. Then,the speed differential and torque differential of the primary and the secondary motors are respectively controlled by using the direct torque control method. Moreover,a simulation model is established with Matlab /Simulink and the corresponding simulation is performed,and the results show that the primary and the secondary motors can achieve torque synthesis control according to the torque change of the combustion engine and the load,at the same time,the inner rotor speed of the primary motor,the secondary motor speed and the actual speed can respectively track the engine speed,the load speed and the target speed well.

Key words: hybrid electric vehicle, dual-rotor motor, direct torque control, Matlab /Simulink
