Efficient optimal sensor placement for structural model based diagnosis
Rosich Oliva, Albert; Yassine, Abed Alrahim; Ploix, Stéphane (2010)
Text en actes de congrés
Accés restringit per política de l'editorialThis work aims to study which sensors are required to be installed in a process in order to improve certain fault diagnosis specifications. Especially, the present method is based on structural models, thus system models ... -
Fault diagnosis based on causal computations
Rosich Oliva, Albert; Frisk, Erik; Åslund, Jan; Sarrate Estruch, Ramon; Nejjari Akhi-Elarab, Fatiha (2012-03-23)
Article
Accés restringit per decisió de l'autorThis paper focuses on residual generation for model-based fault diagnosis. Specifically, a methodology to derive residual generators when nonlinear equations are present in the model is developed. A main result is the ... -
Model-based optimal sensor placement approaches to fuel cell stack system fault diagnosis
Sarrate Estruch, Ramon; Nejjari Akhi-Elarab, Fatiha; Rosich Oliva, Albert (2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe problem of optimal sensor placement for FDI consists in d etermining the set of sensors that minimizes a pre-defined cost function satisfying at the same time a pre-established set of FDI specifications ... -
Optimal Sensor Placement For Fuel Cell System Diagnosis using BILP Formulation
Nejjari Akhi-Elarab, Fatiha; Sarrate Estruch, Ramon; Rosich Oliva, Albert (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents the application of a new methodology for Fault Detection and Isolation (FDI) to a Fuel Cell System. The work is devoted to find an optimal set of sensors for model-based FDI. The novelty is that binary ... -
Optimal sensor placement for leakage detection and isolation in water distribution networks
Rosich Oliva, Albert; Sarrate Estruch, Ramon; Nejjari Akhi-Elarab, Fatiha (2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, the problem of leakage detection and isolation in water distribution networks is addressed applying an optimal sensor placement methodology. The chosen technique is based on structural models and thus it is ... -
Reducing energy consumption in an industrial process by using model predictive control
Caiza Chicaiza, Luis Alberto; Rosich Oliva, Albert; Ocampo-Martínez, Carlos; Benitez, Diego (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés obertIn this paper, we propose to use Model Predictive Control techniques to reduce the energy consumption in an industrial process by incorporating energy consumption restrictions in the problem formulation. We propose to use ... -
Sensor placement for fault diagnosis based on structural models: application to a fuel cell stak system
Rosich Oliva, Albert (Universitat Politècnica de Catalunya, 2011-06-03)
Tesi
Accés obertThe present work aims to increase the diagnosis systems capabilities by choosing the location of sensors in the process. Therefore, appropriate sensor location will lead to better diagnosis performance and implementation ... -
Sensor placement for fault diagnosis performance maximization in distribution networks
Sarrate Estruch, Ramon; Nejjari Akhi-Elarab, Fatiha; Rosich Oliva, Albert (2012)
Text en actes de congrés
Accés restringit per acord de confidencialitatThe success of any diagnosis strategy critically depends on the sensors measuring process variables. This paper presents a strategy based on diagnosability maximization for optimally locating sensors in distribution ... -
