In this paper, the sensorless field-oriented control of asynchronous machine with squirrel-cage rotor (AMS) at the low-speed operation will be observed. The identification of rotor speed from adaptive flux error as well as the adaptation mechanism will be investigated. At first, the background of model reference adaptive system (MRAS) will be revised. Later, the mathematical model of AMS in the stationary...
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...
