An Event-based Approach to Hybrid Systems Diagnosability
A Publication, Prognostics CoE Publications - 10 years, 10 months ago
Shared By: Matthew Daigle
Diagnosability is an important issue in the design of diagnostic systems, because it helps identify whether sufficient information is available to distinguish all the faults. ...

Model-based Prognostics with Concurrent Damage Progression Processes
A Publication, Prognostics CoE Publications - 10 years, 10 months ago
Shared By: Matthew Daigle
Model-based prognostics approaches rely on physics-based models that describe the behavior of systems and their components. These models must account for the several different damage ...
