Voltage Control of a DC/DC Boost Converter Powered by Fuel Cell Stack

This paper deals with control of the DC/DC boost converter fed by PEM fuel cell. The simple PI control and gain scheduling control algorithm are taken in consideration. The PI controller is designed for the operating point determined by the rated voltage and output current. The gain scheduling controller is obtained for the whole control range of the input and disturbance signals. The simulation results shows that PI controller successfully deals with control in one operating point while the gain scheduling controller implemented by the lookup table of the control surface successfully controls the system in the whole range of the input and disturbance signals.
