Distributed fault detection using sensor networks and Pareto estimation
2013 European Control Conference (ECC), 2013 In this paper, a preliminary novel distributed fault detection architecture for dynamic systems using sensor networks and a distributed estimation method based on Pareto optimization is proposed. The goal is to monitor large-scale or distributed systems by using a sensor network where each node acts as a local estimation agent without centralized ...

Sensor Fault-Tolerant State Estimation by Networks of Distributed Observers
IEEE Transactions on Automatic Control, 2022 We propose a state estimation methodology using a network of distributed observers. We consider a scenario in which the local measurement at each node may not guarantee the system’s observability. In contrast, the ensemble of all the measurements does ensure that the observability property holds.
