Abstract:
In view of rotor position and speed estimation scheme, a novel rotor position selfsensing method was put forward by combining the fluctuating high frequency voltage signal injection method and model reference adaptive method, which was used in the sensorless vector control system of the permanent magnetism synchronous motor(PMSM). The speedswitcher was designed to realize smooth switching between the two methods. This method solved the problem that the single method couldn’t give satisfactory balance between static and dynamic performance. The simulation results illustrate the proposed method can reliably realize the sensorless control of PMSM in a wide speed range including zerospeed. The system has good dynamic and static performance.
