Abstract
This paper shows the efficiency of using a sliding mode control of a photovoltaic pumping system, which is strongly non-linear. It contains several non-linear sub-systems (photovoltaic generator, DC/AC converter, an asynchronous three phase motor-pump, centrifugal pumps and two coupled tanks). The mathematical model of the whole system was achieved after the modelling of the various parts constituting it. Furthermore, an FPGA implementation on the map Xilinx Spartan 3A wasperformed to prove the effectiveness of the proposed sliding mode control of the motor-pump angular speed.
