Claim One:
1. A neuro-fuzzy control system for a grid-connected photovoltaic (PV) system, comprising: a solar power array outputting a panel voltage V PV ; a DC-DC converter operably connected to the solar power array; a proportional-integral (PI) controller operably connected to the DC-DC converter, the PI controller controlling a duty cycle of the DC-DC converter; a processor in operable communication with the solar power array, the processor including means for receiving temperature and irradiance information from the solar power array and means for operating an adaptive neuro-fuzzy network, the adaptive neuro-fuzzy network outputting a reference voltage V ref ; and means for applying a reference input to the PI controller, the reference input being characterized by the relation (V ref −V PV ); wherein the maximum power point (MPPT) of the PV array is successfully allocated under varying temperature and irradiance values of the PV array.
