Flux weakening (FW) control is utilized to achieve the optimal current trajectory, thereby weakening the magnetic field and ensuring sufficient output torque of the permanent magnet synchronous motor (PMSM). Nevertheless, conventional methods often face challenges in balancing static accuracy and dynamic responsiveness. This digest proposes a novel FW control strategy integrating an online iterative calculation and voltage feedback regulation, which can obtain the feedforward compensation simultaneously without the pre-defined lookup table, which eliminates the need for a storage table that occupies substantial space of the micro-control unit (MCU). In addition, voltage feedback regulation improves robustness of the system. Experimental verification in an SPMSM drive system confirms the effectiveness of the proposed FW strategy.
