Brief abstract:
This research describes the dynamic behavior of electric traction motors with respect to torque variations and operating noise due to the discrete number of rotor/stator poles. The dynamic characteristics and a mathematical model of the motor as well as the motor controller are derived. The overall model (developed in Matlab/Simulink) will be used to assess, tune and optimize driveline noise and vibrations of vehicles with electric traction motors.
Project schedule:
Jan. 01 2010 - Apr. 27 2010
Publications:A journal paper will be submitted correspondently.
Preliminary Results:
The preliminary results show that direct torque control strategy is key to both torque ripple and operating noise reduction while voltage is selected as the control variable. This method controls torque and flux linkage by selecting the appropriate voltage space vectors based on the relationship between the slip frequency and torque value.
