This paper presents the design and evaluation of a speed control scheme for a DC series motor
supplied by Photovoltaic (PV) system. The proposed design problem of speed controller is formulated
as an optimization problem. Bacteria Foraging Optimization Algorithm (BFOA) is employed to search
for optimal controller parameters by minimizing the time domain objective function. The performance
of the proposed technique has been evaluated with respect to load torque variation, ambient
temperature and radiation. Simulation results have shown the validity of the proposed technique in
cont ling the speed of DC series motor under different disturbances.
