چکیده
A flux observer for induction motors which is adaptive to the active rotor resistance variations presented. Due added fluxes overestimation in structure, global exponential stability properties of current and vector components estimation are ensured under conditions persistency excitation. The proposed has a simpler structure compared existing solutions with properties. simulation results dynamic performance investigation confirm its effectiveness. It shown that even if excitation not met, estimated correctly; consequently, designed can be implemented as an identification algorithm self-commissioning systems electric drives.

Flux observer with online tuning of stator and rotor resistances for induction motors
This paper proposes an adaptive flux observer for induction motors, where stator and rotor resistances are estimated in online environments. The variation of motor parameters during operation degrades the performance of the controller and the flux observer. Among the parameters of induction motors, rotor resistance is a crucial one for flux estimation, and stator resistance also becomes critica...
