A Combined Model-Based and Data-Driven Prognostic Approach for Aircraft System Life Management

A Publication, Prognostics CoE Publications - 8 years, 9 months ago

Shared By: Kai Goebel

Failure prognosis - as a natural extension to the fault detection and isolation (FDI) problem - has become a key issue in a world where ...

An Event-based Distributed Diagnosis Framework using Structural Model Decomposition

A Publication, Prognostics CoE Publications - 10 years, 2 months ago

Shared By: Matthew Daigle

Complex engineering systems require efficient on-line fault diagnosis methodologies to improve safety and reduce maintenance costs. Traditionally, diagnosis approaches are centralized, but these solutions do ...

Distributed Prognostics Based on Structural Model Decomposition

A Publication, Prognostics CoE Publications - 10 years, 2 months ago

Shared By: Matthew Daigle

Within systems health management, prognostics focuses on predicting the remaining useful life of a system. In the model-based prognostics paradigm, physics-based models are constructed that ...

Simulation-based Design and Validation of Automated Contingency Management for Propulsion Systems

A Publication, Prognostics CoE Publications - 10 years, 9 months ago

Shared By: Abhinav Saxena

This paper introduces a novel Prognostics-enhanced Automated Contingency Management (or ACM+P) paradigm based on both current health state (diagnosis) and future health state estimates (prognosis) ...

Automated Contingency Management for Propulsion Systems

A Publication, Prognostics CoE Publications - 10 years, 9 months ago

Shared By: Abhinav Saxena

Increasing demand for improved reliability and survivability of mission-critical systems is driving the development of health monitoring and Automated Contingency Management (ACM) systems. An ACM ...

Improving Multiple Fault Diagnosability using Possible Conflicts

A Publication, Prognostics CoE Publications - 10 years, 9 months ago

Shared By: Matthew Daigle

Multiple fault diagnosis is a difficult problem for dynamic systems. Due to fault masking, compensation, and relative time of fault occurrence, multiple faults can manifest ...

A Comparison of Filter-based Approaches for Model-based Prognostics

A Publication, Prognostics CoE Publications - 10 years, 9 months ago

Shared By: Matthew Daigle

Model-based prognostics approaches use domain knowledge about a system and its failure modes through the use of physics-based models. Model-based prognosis is generally divided into ...
