MODEL REFERENCE ADAPTIVE CONTROL OF PEMFC WITH DC/DC CONVERTER

Maintaining a constant voltage in Proton Exchange Membrane Fuel Cell (PEMFC) has always attracted the attention of many researchers and many articles have been published on this issue. In this paper a state space model of the set made up of a PEMFC and a DC/DC converter is studied, which correlates changes in the fuel cell output voltage to changes in the load current and converter duty cycle. Model reference adaptive control (MRAC) strategy is used to fix cell voltage regardless of the varying system parameters. The model and the controller are simulated in MATLAB/Simulink software and results are compared with a PID controller.
