The objective of this paper deals in introducing how to obtain the rotor flux estimation in real time for induction motor drives. The accuracy of flux estimation algorithm depends on the motor parameters variation. These parameters as stator and rotor resistance vary as temperature changes during motor operation. The practical usefulness of our control models are evaluated and confirmed through experiments using an induction machine (3kW/380V). Experimental investigation tests are provided to evaluate the consistency of the proposed control model using DS1104 with MATLAB - Simulink.
