| Abstract |
This paper proposes a novel model reference adaptive system (MRAS) for speed controlled induction motor drive without shaft sensor, with integral the adaptation mechanism for the on-line tuning of the stator resistance (Rs). In an intent to accurately estimate the ù at low speeds, without deterioration the drive performance, parallel with the ù estimation the Rs is also estimated to compensate Rs thermal variation. The reference model and adjustable model are interchangeable for parallel ù and Rs estimation. For the stator resistance identification, the two models switch their roles. The dynamics of the ù derivation and the Rs estimation are investigated for a wide range of operating conditions and straight forward design procedure is proposed by hyperstability theory. Extensive computer simulation prove the effectiveness of the proposed solution. |
