MODEL-REFERENCE ADAPTIVE FUZZY CONTROL OF HIGH-ORDER SYSTEMS

The paper presents a model reference adaptive fuzzy control scheme whi ch is suitable for high-order systems of well-known structure. It cont ains a hybrid fuzzy controller composed of a nonintegral fuzzy and a p roportional-integral algorithm. The output of the hybrid fuzzy control ler is adjusted by a fuzzy tuning algorithm. The synthesis of the hybr id fuzzy controller and the fuzzy tuning algorithm has been described for the angular speed control problem of the linearized vector control led permanent magnet synchronous motor drive. The computer simulation results have proved the effectiveness of the proposed method showing s table system responses with low sensitivity to large parameter variati ons.
