Motor control method based on data calibration

The invention discloses a motor control method based on data calibration, and belongs to the technical field of motor control, and the method comprises the steps: obtaining corresponding current, voltage and power values at each rotating speed through the calibration of a synchronous motor, including MPTA control data calibration at a rated rotating speed and flux weakening data exceeding the rated rotating speed; according to the method, the UVW output parameter is obtained through the inverse transformation of Clark and Park, so that the control of the motor is achieved, the technical problem of timely adjustment of the control of the final conversion values Id and Iq of the motor is solved, and the method has the characteristics of high torque control precision of the motor, high conversion efficiency of the system, fast response and the like, and is suitable for large-scale popularization and application. According to the invention, the minimum output torque of the motor can be calibrated during no-load,
