Abstract
Induction motor (IM) is a complex controlled object that is difficult to drive and control. In this paper, direct torque control strategy (DTC) is adopted to drive IM. In order to overcome drawbacks of the bad low speed performance of DTC system, Tornambe control (TC) is used to replace the traditional speed regulator to improve system performance. The results show that TC strategy overcomes the disadvantage of the low speed performance declined and improves the response speed of DTC system, and effectively solves the contradiction between the system response speed and overshoot.
