This paper deals with an experimental approach of flux estimation in real time for induction motors drives. Based on the real currents stator, voltages and rotor speed measurements, the rotor fluxes are estimated using different methods. The reduced order model of induction motor is used to offer many advantages for real time identification parameters of the induction machine. The major contributions of this work are: first, avoid the use sensors of direct rotor flux to increase the installation cost and degrade the mechanical robustness. Second, by reducing the order of the induction machine model, the implementation of the proposed real time estimation flux has a good dynamic behavior and therefore is well suited for high performance applications. Third, the estimation of rotor and stator flux can be performed even at variable regime flux and at low loads. Further, the estimation algorithm involves no derivative terms. Finally, we show that the proposed experimental scheme is not sensitive to disturbances parametric errors and it is robust against load variations. The experimental results and the estimated values of fluxes are compared and shown in real time application.
