| Abstract |
A sensorless control of a PM synchronous motor under the parameter variation is presented. The
rotor position is estimated by using the d-axis and q-axis current errors between the real system and
motor model of the estimator. The stator resistance is measured near zero speeds when the motor
changes its rotating direction. The variation of the stator resistance and back emf constant due to the
temperature variation is compensated in the model of the position estimator. The gains in the position
estimator are also adapted according to the motor speeds. |
