초록
A novel flux-weakening scheme for the Interior Permanent Magnet Synchronous Motor (IPMSM) is proposed. This is implemented based on the output of the synchronous PI current regulator-reference voltage to the PWM inverter. Attractive features of this flux weakening scheme include no dependency on the machine parameters, the guarantee of current regulation at any operating condition, and smooth and fast transition into and out of the flux weakening mode without a discontinuity. Experimental results are presented to verify the feasibility of the proposed control scheme.
