Comparative Study a Two Adaptive Observers of Speed and Rotor Flux of the Induction Motor

In this article, a comparative study is being carried out between the extended Gopinath observer (EGO) versus the assembly consisting of the MRAS speed observer and the reduced order Gopinath observer, used in estimating dq components of the rotor flux phasor. Both observers are designed for sensorless vector control systems of the induction motors. Comparative analysis is performed by simulation using the Matlab-Simulink programming environment.
