Model-Based Fault Diagnosis of a NOx Aftertreatment System

The Lean NOx Trap (LNT) is an aftertreatment device used to attain a reduction in nitrogen oxide emissions for Diesel and lean burn engines. The LNT is typically used as a storage device, capturing NOx during lean engine operation. The trap can be regenerated by controlling the exhaust air-fuel ratio to create a rich gas mixture. Under rich conditions, the stored NOx is released and catalytical...

Fault Test Device of Electrical System Based on Embedded Equipment

The electrical system of the construction machinery usually works on circumstance of high temperature, serious vibration and shock, dust pollution as well as electromagnetic interference, so the electrical system is very likely to go wrong while compared with other systems, for example working attachment, under chassis and so on. In view of this, an advanced fault test device, with application ...

PEM Fuel Cell System Robust LPV model-based Fault Diagnosis

In this paper, the problem of robust fault diagnosis in a PEM Fuel Cell (PEM FC) system is addressed. Fault detection is based on a LPV interval observer able to face the variations of parameters with the operating while preserving the linear structure of the model. At the same time, this approach addresses the robustness problem against modeling uncertainty included as unknown parameters whose...
