MRAC based speed regulation of an excitation controlled quick response induction motor

Speed regulation of a voltage decoupled induction motor which provides optimal efficiency and quick response is discussed. A robust first-order model reference adaptive control (MRAC)-based speed controller whose stability has been proved via Lyapunov's second method is proposed. Computer simulation results for a 100-hp squirrel-cage motor show that the proposed MRAC controller has remarkably good tracking and regulation characteristics.<
