Summary:This paper proposes a deadbeat controller applied to direct torque control strategy for a three-phase induction motor. The deadbeat control method uses the discretized dynamic model of the machine to calculate the theoretical stator voltage vector required to reach the references of torque and flux in a single switching period. In this proposal controller, it is used the stator flux and current vectors in the machine model. The induction motor is powered by a three-phase inverter, which is modulated through a vector modulation technique. The experimental results are presented to validate the proposed controller, including low-speed operation.
