ABSTRACT: A state observer is proposed for asynchronous machine; with this observer it possible to observe rotor flux and rotating speed. The gain of this observer involves a design function that has to satisfy some mild conditions which are given. Of particular interest, at the powerful of Field-Oriented Control with the new observer. The control algorithm is studied through simulations and applied in flux and speed profiles , and is shown to be very efficient.

KEYWORDS: Sensorless Speed; High Gain Observer; Field-Oriented Control; Asynchronous Machine.
