The control of a proton exchange membrane fuel cell system (PEM FC) for domestic heat and
power supply requires extensive control measures to handle the complicated process. Highly
dynamic and non linear behavior, increase drastically the difficulties to find the optimal design
and control strategies.
The objective is to design, implement and commission a controller for the entire fuel cell
system. The fuel cell process and the control system are engineered simultaneously; therefore
there is no access to the process hardware during the control system development. Therefore the
method of choice was a model based design approach, following the rapid control prototyping
(RCP) methodology.
The fuel cell system is simulated using a fuel cell library which allowed thermodynamic
calculations. In the course of the development the process model is continuously adapted to the
real system. The controller application is designed and developed in parallel and thereby tested
and verified against the process model. Furthermore, after the commissioning of the real system,
the process model can be also better identified and parameterized utilizing measurement data to
perform optimization procedures.
The process model and the controller application are implemented in Simulink using
Mathworks` Real Time Workshop (RTW) and the xPC development suite for MiL (model-in-theloop)
and HiL (hardware-in-the-loop) testing.
It is possible to completely develop, verify and validate the controller application without
depending on the real fuel cell system, which is not available for testing during the development
process. The fuel cell system can be immediately taken into operation after connecting the
controller to the process.
