Model predictive estimation of evolving faults [PDF]

open access: yes2006 American Control Conference, 2006
In this work we present an optimization based statistical estimation approach for diagnostics in large scale systems. The fault estimation scheme relies on prediction residuals generated by detailed prediction models of the system under consideration. The system dynamics are generally nonlinear.

Optimal Fault Tolerant Control of Large-Scale Wind Turbines in the Case of the Pitch Actuator Partial Faults

open access: yesComplexity, 2020
In this paper, an adaptive fault tolerant control strategy is proposed to deal with the three pitch actuator faults in the large-scale wind turbines. Firstly, a simultaneous state and fault estimation was performed through a suitable LMI (linear matrix ...

Experimental Bayesian Quantum Phase Estimation on a Silicon Photonic Chip [PDF]

open access: yes, 2017
Quantum phase estimation is a fundamental subroutine in many quantum algorithms, including Shor's factorization algorithm and quantum simulation. However, so far results have cast doubt on its practicability for near-term, non-fault tolerant, quantum ...

Fault Impact Estimation for Lightweight Fault Detection in Image Filtering

open access: yesIEEE Transactions on Computers, 2022
Classical redundancy-based fault detection techniques, such as Duplication with Comparison (DWC), rely on replicating thecomputation and comparing the replicas' output at a bit-wise granularity. In many application environments these costs are prohibitive,especially when applications are characterized by an intrinsic level of tolerance.

Sequential Fault-Tolerant Fusion Estimation for Multisensor Time-Varying Systems

open access: yesDiscrete Dynamics in Nature and Society, 2018
In this paper, the impact of the fusion framework on the fault diagnosis process is discussed. The centralized fusion framework makes it difficult to locate and estimate the sensor fault.
