A Comparative Study Between Sliding Mode Control (SMC) and Hybrid Control Fuzzy Sliding Mode (FSMC) for Induction Motor
Résumé
This paper presents a comparative study between twocommand strategies : control by sliding mode (CMS) and thehybrid control Fuzzy sliding mode (FSMC). The sliding modecontroller is applied to an induction motor which offered us aninsensitivity to parameter variations. However this control lawhas a disadvantage of the ‘chattering’ phenomenon. To remedythis problem, we combined the sliding mode control with thefuzzy logic control that the advantages of both strategies areincluded. The application of this controller gave as a gooddynamic, insensitivity to parameter variations and an eliminationof the torque chattering, demonstrated by the simulation results.The comparison of simulated results show that the hybrid controlFuzzy sliding mode (FSMC) is more robust and effective inminimizing the detuning effect in the drive due to parametervariations and model uncertainties.
