“…A plot of the generated torque ξ 1 is shown in Figure 1(c). Notice that, as expected from the results in (De Wit et al, 1996), the mismatch in the estimate of the rotor resistance during the first 5s results in a significant steady-state error both in the flux level and in the generated torque. The convergence of the estimatesτ L andR r to the true values τ L and R r is shown in Figure 1(d).…”

In this paper a new algorithm for estimating the rotor resistance of current-fed induction motors is presented. The proposed method does not require persistent excitation and achieves asymptotic convergence even in the case of zero rotor speed and/or low torque. However, it does require measurement of the rotor speed and flux. To make the scheme practically feasible, a method for estimating the rotor flux is devised. The proposed estimator is combined with an indirect field-oriented control law to achieve torque/speed regulation in the absence of rotor resistance and load torque information. The efficacy of the resulting adaptive output feedback control scheme is tested via simulations.

“…The observer block is hence used to indirectly estimate ARFSV( r ), via the already derived frequency 1 is called Indirect Field-Orientation (IFO). It has been shown in [1] that the CM with IFO is quite robust to model errors with regards to stability. Imperfect parameter estimation by conventional current model leads to deteriorated system performance.…”
