Abstract

In this paper, a novel model reference adaptive system (MRAS) is introduced for estimation of the stator and rotor resistances and rotor speed. The presented MRAS is designed for simultaneous identification of the three quantities in order to save the cost of implementation and processes time. Popov's criterion is used to design the adaptation mechanisms. The validation of the modified technique is tested through Matlab/ Simulink. The results evaluate the effectiveness of the suggested algorithm under load disturbance and parameters variation.
