Sensorless Adaptive Field-Oriented Control Schemes on Asynchronous Machine: A Comparative Study

In this paper, two model reference adaptive control schemes for sensorless field-oriented control application on asynchronous machine will be investigated and comparatively studied. At first, the model of asynchronous machine with defined reference coordinate system as the test plant will be introduced. The general idea of field-oriented control will be revised. Later, concept and key idea of each adaptive control schemes will be discussed. Finally, the comparison in terms of performance, advantages and drawbacks based will be discussed.
