An adaptive control method of sensorless permanent magnet synchronous motor is proposed basedon the grey prediction and model reference adaptive theory. It is given that the basic structure of system controland the estimation of position and velocity. The algorithms of prediction and estimation are introduced. In or-der to realize advanced fast adjustment of speed and improve the response performance of the system, thegrey prediction control is added in the speed loop. The simulation results show that the control system has astrong robustness and adaptability, and it can achieve a good control effect.
