A robust h-infinity controller for an isolated boost converter used in fuel cell application

الملخص EN

In recent years fuel cells have become prominent as an alternative source of energy to meet the society’s energy requirements.

A robust control strategy known as H-infinity control was proposed for an Isolated Boost topology which was mostly used in fuel cell systems.

Converter operation and its detailed mathematical modelling were also presented.

Then the converter with the control strategy suggested is simulated in MATLAB/SIMULINK and compared with other controllers.

The results show that transient response of the converter is very fast and peak overshoot is reduced throughout the load change period with proposed control topology.Keywords: Electricity spot market; bilateral contracts; thermal unit commitment; mixed-integer linear programming.
