Development of torque coordinating control of permanent-magnet motors driving electric vehicle based on identification of yaw-rate controller

In this paper, torque coordinating control based on identification of the yaw-rate controller is proposed for electric vehicle. The control system comprises a fuzzy logic controller that independently controls the wheel torque to prevent vehicle spin. An electric vehicle which is equipped with the permanent-magnet motors has an advantage in terms of control. For example, by generating different torques at the left and right wheels, the vehicle stability in cornering can be improved. Computer simulation using MATLAB/Simulation is carried out to demonstrate the effectiveness of the proposed stability control system.
