  Actuator fault diagnosis of singular delayed LPV systems with inexact measured parameters via PI unknown input observer 

  Hassanabadi, Amir Hossein; Shafiee, Masoud; Puig Cayuela, Vicenç (2017-08-11)
  Article
  Accés obert

  In this study, actuator fault diagnosis of singular delayed linear parameter varying (SDLPV) systems is considered. The considered system has a time-varying state delay and its matrices are dependent on some parameters ...
• Approximating fault detection linear interval observers using -order interval predictors 

  Meseguer Amela, Jordi; Puig Cayuela, Vicenç; Escobet Canal, Teresa (2017-07-01)
  Article
  Accés restringit per política de l'editorial

  Interval observers can be described by an autoregressive-moving-average model while ¿-order interval predictors by a moving-average model. Because an autoregressive-moving-average (ARMA) model can be approximated by a ...

  Chouiref, Houda; Boussaid, B.; Abdelkrim, Mohamed Naceur; Puig Cayuela, Vicenç; Aubrun, C (2017-07-01)
  Article
  Accés restringit per política de l'editorial

  In order to keep away wind turbines from catastrophic conditions due to sudden breakdowns, it is important to detect faults as soon as possible. For diagnosis, a model-based approach is chosen. There are many works that ...

  This paper proposes an approach for the joint state and fault estimation for a class of uncertain nonlinear systems with simultaneous unknown input and actuator faults. This is achieved by designing an unknown input observer ...
• Sensor-fault tolerance using robust MPC with set-based state estimation and active fault isolation 

  Xu, Feng; Olaru, Sorin; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Niculescu, Silviu-Iulian (2017-05-25)
  Article
  Accés restringit per política de l'editorial

  In this paper, a sensor fault-tolerant control scheme using robust model predictive control (MPC) and set-theoretic fault detection and isolation (FDI) is proposed. The robust MPC controller is used to control the plant ...
• Optimal pressure sensor placement and assessment for leak location using a relaxed isolation index: Application to the Barcelona water network 

  Cugueró, Miquel Àngel; Puig Cayuela, Vicenç; Quevedo Casín, Joseba Jokin (2017-06-01)
  Article
  Accés restringit per política de l'editorial

  Water distribution networks are large complex systems affected by leaks, which often entail high costs and may severely jeopardise the overall water distribution performance. Successful leak location is paramount in order ...

  Short-term demand forecast using a bank of neural network models trained using genetic algorithms for the optimal management of drinking water networks 

  Rodriguez Rangel, Hector; Puig Cayuela, Vicenç; López, Rodrigo; Flores, Juan J. (2017-01-01)
  Article
  Accés obert

  Efficient management of a drinking water network reduces the economic costs related to water production and transport (pumping). Model predictive control (MPC) is nowadays a quite well-accepted approach for the efficient ...
• Generalized set-theoretic unknown input observer for LPV systems with application to state estimation and robust fault detection 

  Xu, Feng; Tan, Junbo; Wang, Xueqian; Puig Cayuela, Vicenç; Liang, Bin; Yuan, Bo; Liu, Houde (2017-02-16)
  Article
  Accés restringit per política de l'editorial

  This paper proposes to design an unknown input observer (UIO) for the linear-parameter-varying (LPV) system on the basis of the set theory, which is named as the set-theoretic UIO (SUIO). The advantage of the SUIO consists ...
• Gain-scheduling multivariable LPV control of an irrigation canal system
