Soft Sensor Application to Predict Remaining Useful Life of Components of the Exhaust System of Diesel Engines
In this paper, the application of soft sensors for the estimation of the load on a component as well as the further use of the resulting load-time-signal are described. In the first step the exhaust system of diesel enignes as well as all unput and output variables are characterized. In the following step, the soft sensor is modelled to estimate the load on a component. Furthermore, the derivation of load spectra from the soft sensor and the future usage for the prediction of the remaining useful life are discussed.
