A Markovian jump system approach for the estimation and adaptive diagnosis of decreased power generation in wind farms
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 ... -
Multiobjective performance-based designs in fault estimation and isolation for discrete-time systems and its application to wind turbines
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 ... -
Networked gain-scheduled fault diagnosis under control input dropouts without data delivery acknowledgement
Wiley (2015-03-18)This paper investigates the fault diagnosis problem for discrete‐time networked control systems under dropouts in both control and measurement channel with no delivery acknowledgment. We propose to use a proportional ... -
Performance Tradeoffs for Networked Jump Observer-Based Fault Diagnosis
Institute of Electrical and Electronics Engineers (IEEE) (2015-04)Print Request Permissions In this paper, we address the fault diagnosis problem for discrete-time multi-sensor systems over communication networks with measurement dropouts. We use the measurement outcomes to model the ... -
Robust estimation and diagnosis of wind turbine pitch misalignments at a wind farm level
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
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 ...
