The paper proposes a novel strategy for torque control, namely vector torque control (VTC), taking into consideration the field orient control (FOC) and direct torque control (DTC). It sets up a function to resolve the problem that no definite relation exists between output vector and control variations in the conventional DTC. Also it improves the stator flux model at low speed. In the end, experimental results show that the proposed strategy can improve the output characteristics of induction motor.
