A Neural Inverse Control of a PEM-FC System by the Generalized Mapping Regressor (GMR)

This paper deals with the air management subsystem in fuel cell systems (FCS). It proposes to use a feedforward control action for improving a classical PI control of the FCS for preventing oxygen starvation by using the control scheme suggested by Kawato. This paper therefore, proposes the application of a recent neural network scheme, the GMR (Generalized Mapping Regressor Mapping) to implement a static feedforward controller, which is obtained with the inversion of the FCS model. The idea, for the air management subsystem, is to use a feedforward for optimising a classical PI control of the FCS for preventing oxygen starvation. This control system has been implemented both in numerical simulation and experimentally adopting a properly devised FCS in which the FC stack is realized by a buck-converter (emulator), that is by using a hardware-in-the-loop experimental rig.
