A Markovian jump system approach for the estimation and adaptive diagnosis of decreased power generation in wind farms
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio The Institution of Engineering and Technology (IET) (2019-08-30)In this study, a Markovian jump model of the power generation system of a wind turbine is proposed and the authors present a closed-loop model-based observer to estimate the faults related to energy losses. The observer ... -
Estimation of Nonstationary Process Variance in Multistage Manufacturing Processes Using a Model-Based Observer
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio; Abellán-Nebot, José V. IEEE (2018-08)In this paper, we propose a recursive algorithm to estimate the process variance in multistage manufacturing or assembly processes. We use a replicated model that includes the process variance to be estimated as a time-varying ... -
Moodle questionnaires as a self-assessment tool for meeting the challenges of diversity in students' background knowledge
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio International Academy of Technology, Education and Development (IATED) (2018-11-12)Process Automation and Advanced Control is a subject of the master’s degree in Industrial Engineering from the Universitat Jaume I de Castelló that seeks to develop the students’ ability to design automated production ... -
Multiobjective performance-based designs in fault estimation and isolation for discrete-time systems and its application to wind turbines
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio Taylor & Francis (2019-04-09)In this work, we develop a performance-based design of model-based observes and statistical-based decision mechanisms for achieving fault estimation and fault isolation in systems affected by unknown inputs and stochastic ... -
Performance-based design of PI observers for fault diagnosis in LTI systems under Gaussian noises
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio; Dolz Algaba, Daniel; Sanchis LLopis, Roberto IEEE (2016)This work addresses the fault diagnosis problem for LTI systems under the presence of Gaussian noises through model-based proportional-integral observers with predefined gains. We propose an integrated design of residual ... -
Robust estimation and diagnosis of wind turbine pitch misalignments at a wind farm level
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio Elsevier (2020-02-28)Wind turbine pitch misalignments provoke aerodynamic asymmetries which cause severe damage to the turbine. Hence, it is of interest to develop fault tolerant strategies to cope with pitch misalignments. Fault tolerant ... -
Trade-offs on fault estimation via proportional multiple-integral and multiple-resonant observers for discrete-time systems
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio Institution of Engineering and Technology (2019-03)The authors develop a fault estimation strategy which is based on a novel proportional multiple-integral (PMI) and multiple-resonant observer. This observer is an extension of the well-known PMI observer and it is able to ...
