This work deals with an efficient control of the photovoltaic water pumping system. The suggested method is designed by an indirect field-oriented control based on sliding mode control. The sliding mode control is chosen thanks to its various advantages like robustness versus perturbations and uncertainties as well as high accuracy tracking. The contribution is to attest its good performance with the application of a 1-day irradiation profile to achieve a pumping rate with the same variation to prove the control robustness to variation system parameter such as resistor and inductor rotor variation. The least-squares method algorithm is used for the maximum power point tracking (MPPT) adopted to calculate the speed reference of the induction motor drive of the pumping system from the value of illumination. Finally, to improve sliding mode control efficiency with simulation in MATLAB/SIMULINK environment and experimental results, obtained by real-time implementation in a dSPACE 1104 board.
