Combining learning in model space fault diagnosis with data validation/reconstruction: Application to the Barcelona water network (2014-02-14)
Restricted access - publisher's policyIn this paper, an integrated data validation/reconstruction and fault diagnosis approach is proposed for critical infrastructure systems. The proposed methodology is implemented in a two-stage approach. In the first stage, ...
Leakage isolation using pressure sensitivity analysis in water distribution networks: Application to the Barcelona case study (2010)
Open AccessLeaks are present to some extent in all water-distribution systems. This paper proposes a leakage localisation method based on the pressure measurements and pressure sensitivity analysis of nodes in a network. The ...
Multiple-fault detection and identification scheme based on hierarchical self-organizing maps applied to an electric machine (2019-08-01)
Restricted access - publisher's policyStrategies of condition monitoring applied to electric motors play an important role in the competitiveness of multiple industrial sectors. However, the risk of faults coexistence in an electric motor and the overlapping ...
Open AccessThis paper is related to faults that can appear in multilevel (ML) inverters, which have a high number of components. This is a subject of increasing importance in high-power inverters. First, methods to identify a fault ...
