The paper presents a novel dynamic maximum photovoltaic (PV) power tracking controller using an error driven, error scaled nonlinear self adjusting control (SAC) block for the switching of the Four-Quadrant PWM converter driving the PMDC motor. The novel dynamic controller utilizes reference speed trajectory tracking with supplementary current limiting loop and maximum photovoltaic power tracking loop. It ensures both good reference speed tracking with minimum motor inrush current as well as a near maximum photovoltaic solar energy utilization at all times, especially under varying temperature and solar conditions. The proposed stand-alone photovoltaic renewable energy DC motor drive scheme is suitable for low cost village electricity application in the range of (150 watts to 15000 watts), mostly for water pumping and village irrigation use in arid countries.
