Stator power factor adjustable direct torque control of doubly-fed induction machines

In this paper, a stator power factor adjustable direct torque control of doubly-fed induction machine is proposed. The selection of rotor voltage vectors is performed based on the torque and the stator inactive current. The control system is built and the rotor voltage vector table is given. The feasibility of the proposed control strategy is examined through Simulink simulation experiments. Good control behaviors are obtained
