A Ship Propulsion System as a Benchmark for Fault-tolerant Control

Fault detection and isolation (FDI) methods and algorithms for linear systems is matured during the past decade. However, an extension of these methods/algorithms to the non-linear is necessary, as many industrial processes are of non-linear nature. This paper introduces a propulsion system for (low speed) marine vehicles characterized by it's non-linearity and complexity. The aim is to provide a realistic industrial system for comparison of various FDI methods and experience achievement hereby. The paper describes the benchmark system and requirements to fault detection. Furthermore, a simple version of the system is provided for early design purposes. The model makes it possible to test various methods, compare their properties such as robustness ,and evaluate their effectiveness in the presence of unknown inputs and disturbances.
