More Information
Summary:The invention discloses a surface-mounted permanent magnet synchronous generator flux weakening control method, belonging to the PMSM control technical field. The method employs a current regulator to provide a direct-axis voltage when a motor rotating speed is higher than a base speed, thereby allowing a motor to move along the intersection between a voltage horicycle and a constant torque curve. The method allows a current locus to meet a torque curve, and meanwhile to meet voltage and current restriction; an output direct current voltage can rapidly recover stability after short fluctuation, and possesses sound dynamic response.
