Study of control methodology for single inverter parallel connected dual induction motors based on the dynamic model

摘要

In this paper, a complete close loop system was designed based on the dynamic model. Then, the method proposed in this paper was demonstrated to have a good dynamic characteristic on torque response which was thought to be important in railway traction system. Finally, we improved the performance during the process from unbalanced loads to balanced loads by decreasing the system's sensitivity to some differential quantities when they converged to zero. The validity and effectiveness of this proposed method were confirmed through different unbalanced load tests of simulations and experiments.
