Fuzzy Logic Speed Control for Three-Phase Induction Motor Supplied by Photovoltaic System with a Robust MPPT
electrical machines and drives
This paper proposes a speed control method based on fuzzy logic and conventional PI controller for a three-phase induction motor fed by a photovoltaic generator. The speed for induction motor has been controlled using an inverter driven by space vector pulse width modulation (SVPWM) technique. The SVPWM inverter operates according to the voltage and frequency (V/F) control method. In this work, numerous practical aspects related to the induction motor speed changes operation have been considered. The photovoltaic generator and motor performance is investigated with the maximum power point tracking (MPPT) and without MPPT control. The results of the simulation conducted using the new proposed control method demonstrates the effectiveness of the proposed fuzzy controller compared with the conventional PI controller.
