| titleOfInvention | A kind of built-in permanent magnet synchronous motor control method |
| abstract | The invention relates to a control method of a permanent magnet synchronous motor, in particular to a control method of a built-in permanent magnet synchronous motor. The invention solves the problem that the motor parameters are not used in real time and accurately in the existing permanent magnet synchronous motor control method, so the torque accuracy of the motor output and the motor operation efficiency are affected. The control method of the present invention simultaneously considers the influence of temperature change and motor saturation effect on the motor parameters online, and improves the accuracy of the parameters of the motor at each operating point; the present invention is based on the motor temperature t and the current amplitude i on the feedforward channel. s , current vector angle β online real-time look-up table and MTPA real-time look-up table, the flux linkage calculation model is used on the feedback channel to calculate the flux linkage in real time , the detection equipment for rotor temperature is omitted; and the d -axis current is redistributed using the output result of the torque closed loop and q- axis current , to maintain the permanent magnet synchronous motor to run according to the MTPA trajectory, reducing the heat and loss of the motor. |
