ABSTRACT:

This suggested study consists of the optimisation of the system’s efficiency by using the

artificial neural network (ANN). The data bases of ANN regulator are concluded with MPPT

technique. The drive off line ensures the suitable values of the weights and skews for the

ANN necessary to the system. To facilitate the work of ANN controller, the execution of

learning and recognition programs with a great deal of examples, the choice of the suitable

mathematic equations and the technique of the back propagation helps us to apply it with a

distinctive, simple and highly competent structure. ANN ensures a good robustness of the

control system and a high degree of accuracy. And the average value of global efficiency of

PV pumping system is approximately 97%.
