Networked Fault Detection Systems with Noisy Data Transmission (Vernetzte Fehlerdetektionssysteme mit verrauschter Datenübertragung)

Abstract

In this paper, a networked observer-based fault detection (FD) system is presented. First, the influence of noisy data transmission on the FD performance is analyzed and modeled. Based on it, a design scheme is developed for the construction of observer and residual evaluation unit. The core of this scheme is the integrated design of the coding strategy and FD system. The resulting FD system ensures high fault detectability and low false alarm rate.
