Abstract The parameters of induction motor are affected by temperature, field current and so on, which result in oriented deviation in the rotor flux oriented vector control. Although the algorithm based on reactive power can realize orientation correction, the correction accuracy is affected by the dead zone. Therefore, a modified method is proposed, which based on a closed-loop controller in terms of the dot product of stator current and stator flux. This method is independent of the dead zone and so the orientation correction accuracy is improved. However, the steady-state accuracy is affected by the stator inductance. Hence, a simple compensation algorithm is designed. The theoretical analysis and experimental results verify the effectiveness of the proposed algorithm.

Key words： Stator current stator flux dot product dead zone induction motor electric vehicle
