Assessment of a leak localization algorithm in water networks under demand uncertainty
(International Federation of Automatic Control (IFAC), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialThe performance and success of model-based leak localization methods applied to water networks highly depends on the uncertainty of the system considered. One of the main sources of uncertainty in these networks are the ... -
Closed-loop actuator-fault detection and isolation using invariant set and tubes
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper proposes a new actuator-fault detection and isolation (FDI) strategy for closed-loop discrete time-invariant systems by using invariant sets and tubes. In this approach, invariant sets are used for fault detection ... -
Leak localization in drinking water distribution networks using structured residuals
(2015-08-01)
Article
Accés obertIn this paper, a new model-based approach to leakage localization in drinking water distribution networks is proposed. In particular, a method for generating a set of structured residuals for water distribution networks ... -
Model-based optimal sensor placement approaches to fuel cell stack system fault diagnosis
(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 ... -
Modeling and fault diagnosis of flat inland navigation canals
(2018-05-14)
Article
Accés obertThis article regards the development of an analytical redundancy-based approach for detecting and isolating both sensor and actuator faults in flat inland navigation canals. Inland navigation networks are principally used ... -
Optimal pressure sensor placement for leak localisation using a relaxed isolation index : application to the Barcelona water network
(International Federation of Automatic Control (IFAC), 2015)
Text en actes de congrés
Accés obertWater distribution networks are large complex systems that are affected by leaks, which often entail high costs and may severely jeopardize the overall water distribution performance. Successful leak localisation is paramount ... -
Set-membership parity space hybrid system diagnosis
(2014-11-07)
Article
Accés obertIn this paper, diagnosis for hybrid systems using a parity space approach that considers model uncertainty is proposed. The hybrid diagnoser is composed of modules which carry out the mode recognition and diagnosis tasks ... -
Set-valued observer-based active fault-tolerant model predictive control
(2017-09-01)
Article
Accés obertThis paper proposes an integrated actuator and sensor active fault-tolerant model predictive control scheme. In this scheme, fault detection is implemented by using a set-valued observer, fault isolation (FI) is performed ... -
State estimation and decoupling of unknown inputs in uncertain LPV systems using interval observers
(2017-06-13)
Article
Accés obertThis paper proposes a linear parameter varying (LPV) interval observer for state estimation and unknown inputs decoupling in uncertain continuous-time LPV systems. Two different problems are considered and solved: (1) the ...
