MODELING AND CONTROL SOLUTIONS FOR ELECTRIC VEHICLES

Abstract

This paper extends previous work and proposes modeling and control solutions for electric vehicles, detailed and accurate mathematical models and corresponding simulink models, of both electric vehicle's electric machine and platform sub-systems was derived, coupled with the wheel rotational velocity via characteristics of the electric machine and surface conditions. Different control schemes including one and two loops control, was designed and tested to result in smooth driving for comfortable riding, to cope with different requests including reference signal variation and disturbances in the form of changes in the total mass and road surface conditions. The proposed models was created and verified using MATLAB/simulink software.
