Patent ID: 10714766

Abstract:
The aim of the invention is to allow a precise and quick regulation of the influencing variables in the operation of a fuel cell. A regulator is used for the regulation, said regulator being designed on the basis of a model of the gas conditioning unit in the form of a coupled nonlinear multivariable system in that the coupled nonlinear multivariable system is decoupled and linearized using Lie derivatives, and the regulator is designed for the decoupled linear multivariable system. The regulator calculates the control variables (uG, uS, uN, Q) for at least three present actuators of the influencing variables of the gas conditioning unit at each sampling time of the regulation using specified target variables (yj,dmd), and at least the three actuators of the gas conditioning unit adjust the calculated control variables (uG, uS, uN, Q) at each sampling time of the regulation.
