Abstract

Inland navigation networks are composed of in- terconnected navigation reaches. Some of them are flat and thus especially subject to resonance phenomena: lock operations create waves that can travel back and forth during several hours before their attenuation. The objective of this paper is to propose a model dedicated to this phenomenon, which is called multiple Integrator Delay Zero (mIDZ) model. It is based on the well known IDZ model, which is particularly suitable to reproduce the dynamics of free-surface water systems. However, since it is a first order model, it can only reproduce the effect of the first peak and not the effect of the subsequent, attenuated peaks that are observed in the response. The proposed model exploits the performance of the IDZ model in order to reproduce the effect of the following peaks. Its design requires the classical IDZ parameter identification followed by a frequency study to determine the attenuation and the periodicity of the signal. This thorough study aims at obtaining an accurate model that can be used for fault diagnosis and/or fault-tolerant control purposes. The proposed approach is illustrated by considering the Cuinchy- Fontinettes navigation reach located in the north of France.
