Abstract
The invention provides a control method for a self-starting permanent magnet synchronous motor, and the method comprises the following steps: inputting a required torque value, and measuring the stator current and rotor speed of the motor; a real-time stator flux linkage state quantity and a real-time rotor flux linkage state quantity are obtained through a flux linkage measurer; changing the state quantities of a real-time stator flux linkage and a real-time rotor flux linkage according to the required torque value quantity, and controlling the movement directions of the real-time stator flux linkage and the real-time rotor flux linkage; and changing the inclination angles of the real-time stator flux linkage and the real-time rotor flux linkage, obtaining modification parameters of the inclination angles, and controlling the torque of the motor.
