A Comparative Study Between Sliding Mode Control (SMC) and Hybrid Control Fuzzy Sliding Mode (FSMC) for Induction Motor

摘要: This paper presents a comparative study between two command strategies: control by sliding mode (CMS) and the hybrid control Fuzzy sliding mode (FSMC). The sliding mode controller is applied to an induction motor which offered us an insensitivity to parameter variations. However this control law has a disadvantage of the ‘chattering’phenomenon. To remedy this problem, we combined the sliding mode control with the fuzzy logic control that the advantages of both strategies are included. The application of this controller gave as a good dynamic, insensitivity to parameter variations and an elimination of the torque chattering, demonstrated by the simulation results. The comparison of simulated results show that the hybrid control Fuzzy sliding mode (FSMC) is more robust and effective in minimizing the detuning effect in the drive due to parameter variations and model uncertainties.
