Abstract
To effectively drive the sensorless high frequency permanent magnet synchronous motor (HF-PMSM) within the whole range of speed, the dual mode control of the ten pole pairs HF-PMSM is proposed. Based on the equivalent hardware configuration of the HF-PMSM drive, the typical space vector pulse width modulation for the sinusoidal-wave drive mode is utilized as the startup strategy. The sensorless variable voltage and variable frequency control algorithm is carried out simultaneously. The sensorless six-step square-wave drive mode based on three-phase inverter bridge pulse width modulation is utilized at the high frequency operation. The key rotor commutation position is detected with the phase back electromotive force method. The three phase voltages are obtained by the divider resistances and filter capacitances in the designed zero crossing point detection circuit. Then the commutation signals are detected by the designed detection circuit and software phase shift compensation. The simulation results show that the proposed control method is effective.
