摘要
PURPOSE: A model based sensor-less vector control method of PMSM using an adaptive observer is provided to accurately estimate the position of a magnetic pole of a permanent in emergency case without a sensor.;CONSTITUTION: A coordinate current differential equation model based on the position of a magnetic pole which is estimated based on a mathematical model of a permanent magnetic model is designed. An adaptation observation apparatus is configured in consideration of a position error and a speed error based on a current and voltage supplied to the motor. The position error of a magnetic pole is obtained by using the adaptive law of the adaptation observation apparatus. The position of the magnetic pole of a synchronous motor is estimated by using PLL(Phase Lock Loop).;COPYRIGHT KIPO 2011
