Abstract：The flux-weakening control scheme with one single current regulator has the advantage of simplicity and fast dynamic response, which is a competitive candidate in practice for control of permanent magnet synchronous motors (PMSM). Besides, it can effectively avoid the saturation issue of the traditional flux weakening control scheme with two current regulators when the PMSM runs at very high speed. Despite these advantages, it cannot fully use the output voltage of the motor, and high loading capacity and high efficiency are difficult to be realized simultaneously. To overcome the drawback, a single current regulator based on virtual resistor is proposed in this paper to realize the flux-weakening control, which achieves the ability of high dynamic response, high efficiency, and high loading capacity at the same time. Eventually, simulation and experimental results validate the effectiveness of the proposed control strategy.
