Analysis of the Sensorless PMSM Control Technique in the Full Speed Section

Abstract:

A novel position sensorless control strategy integrated with full section and high precision for a permanent magnet synchronous motor (PMSM) applied to wind power pitch was proposed in the paper. Based on high frequency signal, where three-phase triangular carrier spwm is injected and the state current response is detected to accurately estimate the rotor position in the still and low speed, which doesn’t rely on the non-ideal features. Based on BEF PMSM mathematic model, the phase locked loop technique is used to accurately detect the rotor position in the middle and high speed. the Finally, experiment on a 10 KW pith system demonstrates that the proposed method is effective and is capable of achieving more accurate control in the full speed section.
