Fractional Order PID Design for a Proton Exchange Membrane Fuel Cell System Using an Extended Grey Wolf Optimizer

This paper presents a comparison of optimizers for tuning fractional-order proportional-integral-derivative (FOPID) and (PID) controllers, which were applied to DC/DC boost converter. Grey wolf optimizer (GWO) extended grey (EGWO) have been chosen achieve suitable parameters. strategy aims improve optimize proton exchange membrane fuel cell (PEMFC) output power quality through its link with the The model controllers implemented in MATLAB/SIMULINK environment. study has conducted compare effectiveness proposed transient, accuracy tracking reference current, steady-state, dynamic responses, overshoots, response time. Results showed that combination EGWO-FOPID had significant advantages over rest optimized controllers.
