摘要: The paper presents a novel dynamic maximum photovoltaic (PV) power tracking controller using an error driven, scaled self-adjusting sliding mode for PV energy utilization in low cost stand-alone resort/village electric supply scheme. utilizes motor speed trajectory loop with additional loop. This ensures both good and near at all times, especially under varying ambient temperature (Tx) solar irradiation (Sx) conditions. proposed requires only the array output voltage current signals DC that can be easily measured. Satisfactory results are obtained dual feeding resistive loads (lighting heating) as well PMDC motor. (photovoltaic renewable scheme is suitable electricity applications range of (150 watts to 15000 watts), mostly water pumping, heating, lighting village irrigation use arid developing countries
