Summary

To improve the control performance of parallel connected induction motors fed by a single inverter in high speed train under different wheels radius and various adhesion, a novel control strategy based on the weighted vector control is proposed. In this paper, a weighted flux linkage vector model of dual induction motors is developed, and then the control expressions of weighted rotor flux linkage and summation torque are derived. And then a adhesion control method combined optimum adhesion control and weighted vector control is proposed. The weighted value of vector control is distributed automatically according to the wheels radius and adhesion condition of each motor. The simulation results prove that the proposed method can decrease the torque difference of each motor caused by different wheels radius and increase the summation torque under the slip/skid situation.
