PEMFC voltage control using PSO-tunned-PID controller

This paper presents a PID control which is tuning by Particle Swarm Optimization to control the output voltage of the most-used fuel cell type, namely, Proton Exchange Membrane Fuel Cell (PEMFC). In this paper, PEMFC voltage is controlled for load changes in a simple study system. PID controller is used in control system for the fuel cell plant for these variations in terms of the input current into the membrane (I_st). The study plant tries to keep constant the output voltage of a fuel cell in the specific required amount. Simulations were carried out in MATLAB/SIMULINK environment. The obtained results verified the high performance capability of the proposed PSO-based tuning of a PID controller to achieve the mentioned goals.
