초록
Speed and position sensors require the additional mounting space, reduce the reliability, and increase the cost of motor. Various control algorithms have been proposed for the elimination of speed senor. This paper compares several schemes of MRAC for field-oriented control of induction motor without speed and flux sensors. These schemes are based on observing the fluxes, the counter EMF, and the instantaneous reactive power of motor. A review of these schemes of MRAC is presented. Then sensorless drives using each estimation method are compared through simulation and experiment.
