Resumen:
The article addresses the LPV control of a PolymerElectrolyte Membrane Fuel Cell (PEMFC). In order to optimizeefficiency, PEMFCs require reliable control systems ensuringstability and performance, as well as robustness to model uncertaintiesand external perturbations. On the other hand, PEMFCspresent a highly nonlinear behavior that demands nonlinearand/or adaptive control strategies to achieve high performancein the entire operating range. Here, a linear parameter varying(LPV) gain scheduled control is proposed. The control is basedon a piecewise affine LPV representation of the PEMFC, a modelthat can be available in practice. In order to deal with the saturationof the control action, an LPV anti-windup compensation isalso proposed. The complete control strategy is applied to severalexperimental practical situations in a laboratory fuel cell systemto evaluate its performance and the reliability of the proposedalgorithms.
