Direct torque control of induction motor with fuzzy stator resistance adaptation
Résumé
A new stator resistance estimator using fuzzy logic is proposed. The input variables of the fuzzy logic identifier are the input and output of the low-pass (LP) filter used to integrate the back-emf. Simulation results, using Matlab-Simulink, comparing the fuzzy estimator and a classical integrator in a direct torque control (DTC) scheme prove the superiority of the novel approach. The stator flux locus is smoothed and therefore torque ripples are reduced.
