The Study Of Variable Structure Control For AC Motor Control System Of Electric Vehicles

The paper summarizes the current issues of electric vehicle (EV) of the world, and the drive system of EV, including the motor, controllers, batteries, switch components has been chiefly discussing. On this foundation, has put forward the basic train of putting the Variable Structure Control(VSC) on the drive system of EV.The paper introduces the application of the VSC based on the Vector Control Hysteresis in the drive system of EV; Studies the scheme of drive control of EV.; Discusses the correlation theory that the VSC was applied in the drives control of EV; Designs the entire settlement scheme of VSC. The simulation study has been in progress to the control scheme by application MATLAB/SIMULINK.In c onclusion, the paper analyses the excellent and shorting shortcoming of the entire settlement scheme of VSC. Some useful conclusions was draw from it, All these were the theory foundation and basis for developing practical search of the paper.
