| titleOfInvention | A current operating point given system and method for a permanent magnet AC motor |
| abstract | The present application discloses a current operating point given system and method for a permanent magnet AC motor. The system includes: a pseudo-model feedback system for using the final given value of the direct-axis current and the final given value of the quadrature-axis current of the previous control beat. The fixed value is used as the input, so that the current operating point given system of the permanent magnet AC motor is decoupled from other control systems, and the bandwidth of the torque controller can be designed to be very high, so as to realize the difference between the parameters of the permanent magnet motor and the estimated output torque. Feedback; torque controller, used to achieve fast and high-precision output of torque, MTPA solving unit, used to accurately calculate the MTPA curve under different loads; field weakening operating point switching unit, used to realize the switching between field weakening control and MTPA control Balance, and the field weakening control part can also be decoupled from other control systems, thereby improving the response speed of the field weakening control. By means of the present application, the current operating point setting of the permanent magnet AC motor can be quickly and effectively performed, and the control performance in the entire working area of the permanent magnet motor can be improved. |
