Abstract :
A design methodology for the full-order flux observer and model reference adaptive mechanism (MRAS) to estimate flux linkages and rotor speed of the dual stator winding induction motor that ensures system stability under all operating conditions is set forth. The Butterworth polynomial and D- decomposition techniques are used to select observer and speed controller gains. Computer simulation results of the controlled sensor-less drive system confirm the adequacy of the proposed full-order flux observer and speed estimation scheme evidenced by the accurate rotor speed regulation.
