Health Monitoring of Hybrid Systems Using Hybrid Particle Petri Nets
This paper presents an approach of model-based diagnosis for the health monitoring of hybrid systems. These systems have both continuous and discrete dynamics. Modified Particle Petri Nets, initially defined in the context of hybrid systems mission monitoring, are extended to estimate the health state of hybrid systems. This formalism takes into account both uncertainties about the system knowl...
متن کاملFramework for a Hybrid Prognostics
Fault detection and isolation, or fault diagnostic, of physical systems has been subject of several interesting works. Detecting and isolating faults may be convenient for some applications where the fault does not have severe consequences on humans as well as on the environment. However, in some situations, detecting and diagnosing faults may not be sufficient. In these cases, it is more inter...
متن کاملPrognostics 101: A tutorial for particle filter-based prognostics algorithm using Matlab
This paper presents a Matlab-based tutorial for model-based prognostics, which combines a physical model with observed data to identify model parameters, from which the remaining useful life (RUL) can be predicted. Among many model-based prognostics algorithms, the particle filter is used in this tutorial for parameter estimation of damage or a degradation model. The tutorial is presented using...
متن کاملTechnology Assessment of Sensor Systems for Prognostics and Health Monitoring
Data collection is an essential part of a prognostics and health monitoring approach and often requires the use of sensor systems to measure the environmental and operational parameters of a product or system. A survey is presented on the commercial availability of sensor systems that can be used for monitoring electronic products and systems. From the results of our survey, characteristics of ...
متن کاملEmbedded Prognostics Health Monitoring
The Pacific Northwest National Laboratory (PNNL) has conducted R&D for the US Army on prognostics health monitoring (PHM). The main focus of the work was to demonstrate the feasibility of developing an onboard PHM system for the gas turbine engine used on the M1 Abrams tank. Research was performed on methods for real time, onboard prognostics/engine life expectancy forecasting, and a prototype ...
