Hydrographical networks are large and complex systems used to meet the needs of mankind in terms of irrigation, transport, water supply, and responses to the needs of industries. The long-term response to these requirements has resulted in structures and measurement systems that are generally remote, enabling the implementation of strategies for the efficient management of water resources. However, in an increasingly constrained context, notably due to changes in water demand, resource depletion and climate change, the management of hydrographical networks must be carried out optimally. One of the possibilities consists in designing tools which allow the efficient control of the structures. However, the use of these tools requires the provision of reliable data and the commands can only be applied correctly if the actuators are not impacted by faults. It is therefore necessary to design supervisory methods that enable the detection and prediction of faults and then fault-tolerant control strategies in order to ensure the response to the management objectives. Furthermore, these networks have a large number of sensors and actuators spatially distributed and connected, which makes difficult the design of centralized fault detection (FDI) and/or fault-tolerant control (FTC) strategies. For this reason, advanced techniques in fault diagnosis and fault-tolerant control using the distributed approach will be proposed to guarantee an efficient and reliable management. These techniques will be applied on the inland waterways in the north of France.
