چکیده
The photovoltaic powered water pumping system investigated in this paper consists mainly of a photovoltaic generator, a boost converter, a tension inverter and a centrifugal motor-pump Then, we present a method which resolved the problem of input/output linearization of the nonlinear system from his mathematical model, this technique is associated to the Maximum Power Point control which depends on meteorological conditions (insulation and temperature) and the Results of simulation are given for various variables of the structure in the closed loop. Finally, we present the implementation of the MPP control in a kit based STM32 micro-controllers and the measurements were carried out on the experimental system that enabled us to validate the adopted control.
