Abstract: In this paper, an intelligent controller applied to renewable energy system has been discussed. The attractiveness of the photovoltaic generators (PV arrays), as a renewable power source is that they produce a clean energy without running costs. This fact in addition to the continuous reduction in the PV arrays initial cost and the increase in their efficiency imply the promising future of the PV generation systems. The PI-controller gains are accurately identified and hence it proved its ability in driving the PV module to its maximum power point in terms of majority of the performance measures. This leads to a significant increase in the delivered power, especially when the direct coupling operating point is far from the maximum power one.
