Running Example: the 2-Tank System

Abstract

A simple system will be used as a running example throughout the manuscript. It serves to illustrate typical faults and the resulting reconfiguration approaches. The example is a reduced version of the popular Three-Tank Benchmark Problem first described by Heiming and Lunze [1999]. The system contains two tanks connected by a valve and filled by a pump. The goal is to maintain a constant outflow of the system, which requires a constant level in the right tank. Although the system is simple (see Fig. 3.1), it is sufficient to demonstrate the relevant effects encountered with respect to reconfiguration.
