This paper presents a robust output feedback controller based on sliding modes and indirect adaptive control applied to the angular shaft speed control of a three-phase induction motor. This approach has remarkable stability properties and offers a straightforward and intuitive tuning of its parameters. Moreover, a simplified version of the algorithm, named compact indirect variable structure model reference adaptive control (CIVS-MRAC), provides not only an easy design procedure, but also a computational implementation of low complexity, thus motivating its application in industrial environments.
