Abstract: In this paper a durable flux-weakening control strategy is introduced. Based on this control strategy a vector control of an interior permanent magnet synchronous motor drive is implemented. The new field-weakening control scheme is introduced based on the space-vector modulation technique, that deals with the problem of the dc-link voltage not being fully utilized. The switching of field-weakening is decided using the duty-time of the zero-voltage vector that is set as a feedback signal. A Matlab/Simulink is used to generate the new control scheme. The results show that the proposed scheme is attainable. Since the motor operates in two modes the proposed control scheme has shown a smooth transition between the constant-torque region which is below the base speed and the constant-power region that is above the base speed.
