Ac Induction Motor

Aiming to solve the energy saving problem in modern electric vehicle, we propose a motor-generator integration control system based on the induction motor and the fuzzy control theory in this paper. A motor-generator hardware platform is built up using the four quadrant characteristic of AC induction motor. The AC induction motor works both as driving motor of the electric vehicle and as well as the energy recovery generator. Specifically, the fuzzy direct torque control strategy is adopted in the motor state, and fuzzy instantaneous torque control strategy in power generation state. A simulation is carried out to analyze the practicality of the proposed control method, the simulation results show that the fuzzy torque control technology is well performed. Finally, a simulative energy recovery experimental platform is built up to test the proposed integration control system, and results shown that the efficiency of energy recovery could be up to 97.3%.

Control Signals

The advantages and shortcomings of three-level voltage source inverters to be applied on locomotive traction electric drives are highlighted in relation to two-level ones. To protect wheels from slipping on rails, the control system is designed. The control system with protection from slipping uses system of direct torque control as the subordinated contour to produce control signals on voltage source inverter. The topology and principles of operation of both protections from slipping and direct torque control of traction induction motor with three-level voltage source inverters are described. The simplified structure of mechanical part of traction drive using basic and axle suspension is considered. The adequacy of designed control system is confirmed by means of Matlab, the results of mathematical modeling show a high convergence with the results of physical model of traction drive.
