This paper focuses on the design of a controller for a low temperature ethanol steam\udreformer for the production of hydrogen to feed a protonic exchange membrane (PEM) fuel\udcell. It describes different control structures for the reformer and treats the control\udstructure selection of this multiple input multiple output (MIMO) system. For each\udconsidered control structure, decentralised 2 2 controllers with proportional integral (PI)\udcontrol actions in each control loop are implemented. The tuning of the PI parameters and\udthe performance evaluation of the different controllers are based on a non-linear simulation\udmodel. For the validation and comparison of the considered controllers, the dynamic\udresponse for different setpoint changes and initial conditions is analysed, as well as the\udbehaviour of the controlled system against disturbances.
