Abstract :
The detection accuracy of rotor position will affect the control precision in permanent magnet synchronous motor control system. The resolver/digital converter detection method is widely applied in permanent magnet synchronous motor control system. The paper presents an effective method of selecting the resolution of resolver/digital converter. This paper describes the specific parameters of AD2S1200 chip, which is adopted to verify the method. The experimental results show that this selection method is effective and reliable.
