    The purpose of this paper is to design a Fault Detection and Isolation (FDI) system based on interval LPV observers with application to a real fuel cell. The interval LPV observer is used to generate an adaptive threshold to enhance the robustness of the fault detection test. Real field data and system identification techniques are used to identify the nominal model as well as its uncertainty. Since fuel cells are highly non-linear systems when operating in their whole range of operation, a LPV model is used. Finally, fault isolation is based on an algorithm that uses the residual fault sensitivity. Several fault scenarios are used to show the performance of the proposed approach.

    In this paper, the modelling of an energy generation system based on polymer electrolyte membrane fuel cell (PEMFC) system through a parameter varying approach (LPV model), that takes in to account model parameter variation with the operating point, is presented. This model has been obtained through a Jacobian linearization of the PEMFC non-linear dynamic model that was previously calibrated using real data from lab. In order to illustrate the use of the LPV model obtained its application to model-based fault detection is used. For this purposes a set of common fault scenarios, which could appear during a normal PEMFC operation, is used as case study.

    En este trabajo se presenta un modelo dinámico de una pila de combustible tipo PEM comercial (Ballard Nexa 1.2 kW) así como la calibración experimental de sus parámetros a partir de dados reales de laboratorio. La calibración se realiza resolviendo el problema de ajuste de datos de un sistema real (datos de laboratorio) utilizando un proceso de optimización por mínimos-cuadrados no-lineales.. Finalmente, se ha implementado un simulador a partir del modelo calibrado experimentalmente que ha permitido contrastar la bondad del modelo comparándolo con el comportamiento real del sistema.

    In this paper, a model-based fault diagnosis methodology for PEM fuel cell systems is presented. The methodology is based on computing residuals using an LPV observer. Sensor fault detection faces the problem of robustness using adaptive thresholds generated with interval observer. Fault isolation is performed using the Euclidean distance between the observed relative residuals and theoretical relative sensitivities. To illustrate the results, a commercial fuel cell Ballard Nexa© is used in simulation where a set of typical fault scenarios have been considered. Finally, the diagnosis results corresponding to those fault scenarios are presented. It is remarkable that with this methodology it is possible to diagnose all the considered faults in contrast with other well known methodologies which use the classic binary signature matrix approach.

    En este trabajo se presenta el modelado de un sistema generador de energía basado en pilas de combustible PEM mediante un modelo variante con el punto de operación (modelo LPV). Dicho modelo ha sido obtenido mediante la linealización del modelo dinámico no lineal que ha sido previamente calibrado con datos reales de laboratorio. El modelo LPV obtenido está pensado para ser utilizado en el diseño de controladores y algoritmos de diagnóstico de fallos basados en modelos.
