- Abstract:
- In view of to the conventional problem that when motor is running at low speed rotor position detec-tion is inaccurate,the method of high frequency signal injection was studied to deal with a new sensorless con-trol technology to detect the rotor speed and position information. High frequency signal injection method inpermanent magnet synchronous motor sensorless control theory was discussed in detail，the filter and hetero-dyne link were designed , and the rotor observer was built to acquire the information of rotor speed and posi-tion ， a simulation of low speed was focused on. The simulation results show that sensorless control technologybased on high frequency signal method is applicable to low speed,and accurately detect the rotor speed andposition information.
