They are impacted by extreme events that should be bigger due to climate change. By focusing on extreme rainy events, the amount of water in excess has to be dispatched on all the network to avoid flood, and then rejected to the sea heeding the tides. Pumps can also be used to reject the water to the sea but they lead to big operating cost. To deal with this challenging issue, the modelling tools and the water asset management strategies that have been recently proposed are adapted and improved in this paper. They consist in an integrated model, a flow-based network and a quadratic optimization based on constrains. The efficiency of this water management strategy requires an accurate predictive rainfall/runoff model. It is highlighted by considering a realistic case study that is also used to describe all the methodology step.

In this work, the quadruple-tank system has been considered. For this process, a precise control benchmark was available and worked on previously. To ensure the asymptotic stability of this nonlinear system, we made a discretized linearized model and applied a centralized MPC controller with terminal cost constraint. The effectiveness of the proposed strategy is illustrated by simulations.

This system has the particularities to have large scale dimension, without slope, with several inputs and ouputs, and thus difficult to be modelled according to classical modelling methods. For recent years, it was equipped with level sensors in order to have better knowwledge of its behavior, to detect its state online and thus improve its management. However, level sensors are subjected to measurement or transmission errors, setting errors, and quick or slow drifts. In order to detect these sensor errors, a classification approach is proposed. It appears adapted to the fault detection of large scale hydraulic systems without model. The classification approach is used on data measured from 2006 to 2009. The first results and analysis show that the classification method is effective for addressing the problem of sensor fault detection.

The proposed approach is based on the identification of the parameters characterizing the system without any a priori knowledge. Our contribution consists in developing a specific identification scheme that is insensitive to a certain type of faults. The identified parameters are then invariant to the presence of actuator or sensor faults. Thereafter, a fault estimation procedure is proposed in order to detect sensor or actuator faults. The paper ends with a simulation example which highlights the effectiveness of the proposed approach.

Il s'agit a partir de modèles climatiques couplésà des modèles hydrologiques de prédire l'état de la ressource sur des horizons futurs allant jusqu'à la fin du siècle, en considérant plusieurs scénarios de changement climatique. Cette démarche n'est pertinente qu'à la condition de disposer de modèles climatiques et hydrologiques fiables et de méthodes permettant de réduire l'incertitude liéeà l'utilisation de chaque modèle. Dans le cas contraire, l'étude de la résilience des voies navigables peutêtre effectuéeà partir d'un modèle volumique représentant leur dynamique. Il s'agit d'un modèle intégré de réseaux de voies navigables qui permet la modélisation de leur dynamique tout en considérant la possible influence des bassins versants et des nappes phréatiques. Ce modèle est basé sur le bilan journalier des volumes d'eau entrant et sortant de chaque bief du réseau. Il est utilisé afin d'étudier les conditions limites du bon fonctionnement des réseaux de voies navigables en période d'étiage. L'approche proposée est illustrée dans le cadre du réseau de navigation du Nord-Pas de Calaisà partir de données réelles.

These data acquisition and control systems lead to the improvement of the management of these networks. Moreover, they allow the implementation of more accurate automatic control to guarantee the navigation requirements. However, sensors and actuators are subject to faults due to the strong effects of the environment, aging, etc. Thus, before implementing automatic control strategies that rely on the fault-free mode it is necessary to design a fault diagnosis scheme. This fault diagnosis scheme has to detect and isolate possible faults in the system to guarantee fault-free data and the efficiency of the automatic control algorithms. Moreover, the proposed supervision scheme could predict future incipient faults that are necessary to perform predictive maintenance of the equipment. In this paper, a general architecture of sensor fault detection and isolation using model-based approaches will be proposed for inland navigation networks. It will be particularized for the Cuinchy-Fontinettes reach located in the north of France in order to show the effectiveness of the proposed fault diagnosis scheme. The preliminary results show the effectiveness of the proposed fault diagnosis methodologies using a realistic simulator and fault scenarios.

Furthermore, it integrates a control module that allows implementing basic controllers. For more complex approaches, developers from the automatic control and artificial intelligence (AI) communities usually design, implement, and test new algorithms using dedicated software such as MATLAB. However, models of hydraulic systems employed in MATLAB are often very simple. The main objective of the paper is to design a simulation architecture by coupling HEC-RAS with MATLAB, thus improving the accuracy of the dynamics of the hydraulic systems considered in the control simulations. The main feature of the MATLAB HEC-RAS interface design is that it allows one to execute customized code at regular time intervals during the simulation. In this way, closed-loop control and optimization algorithms c...

These reaches are generally characterized by negligible bottom slopes and large time delays. The latter requires ensuring the coordination of the current control actions and their delayed effects in the network. Centralized control strategies are often impractical to implement due to the size of the system. To overcome this issue, a distributed Model Predictive Control (MPC) approach is proposed. The system partitioning is based on a reordering of the optimality conditions matrix, and the control actions are coordinated by means of the Optimality Condition Decomposition (OCD) methodology. The case study is inspired by a real inland waterways system and shows the performance of the approach.

This strategy requires a modelling method of the network based on a weighted digraph of instrumented points, and the definition of resource allocation and setpoint assignment rules. Two setpoint assignment rules are designed and evaluated in the case of an open-channel system composed of one difluent and one confluent showing their effectiveness.

These features pose challenging problems at the modeling and controller design stages. A control-oriented model is derived in this work, which allows to handle these issues in a suitable manner. A predictive control scheme is developed to ensure the coordination of the control actions and their delayed effects in the system. The proposed approach is tested on a case study to highlight its performance, and it is shown that it is possible to guarantee the navigability condition of the waterways as well as other operational goals.

These canals are particularly subject to resonance phenomena, which can create waves such that the navigation condition might not be guaranteed. It is therefore required to ensure dealing with freefault measured data and actuators. In this work, a fault detection and isolation method based on the Integrator Delay Zero model (IDZ) is designed for flat navigation canals. The proposed method is dedicated to the detection and isolation of sensor and actuator faults. Finally, it is tested by considering the Cuinchy-Fontinettes canal located in the north of France.

The considered systems are characterized by large scale networks where each diffluence is equipped with a control gate and a measurement point. Modelling methods of the networked hydrographical systems with equipped diffluences are presented. The proposed strategy, based on a supervision and hybrid control accommodation approach, requires generic resource allocation and setpoint assignment rules. The simulation results show the effectiveness of the reactive control strategy.

This system is a large scale system with several inputs and outputs that nowadays is operated manually and with local controllers that try to maintain the level of the channel as close as possible to the NNL and fulfils the seaworthiness requirements. For recent years, the channel has been equipped with electronic sensors in order to have better knowledge of its behaviour, provide online the state to the lockkeepers and improve its management. In this work, an automatic control based on a Model Predictive Controller (MPC) is proposed. The MPC controller is based on a model of the system and, with the available data, provides automatically the suitable control inputs (flows) in order to maintain the level in all the points of the channel despite the locks operation that produces wave phenomena and other ...

Several solutions of water asset management based or not on optimization and control exist but they require primarily on a good prediction of the volumes triggered by rainfall after a storm. Numerous studies are dedicated to this challenging issue that have this main objective of how to predict the runoff by using the right model with taking into account the nonlinearities induced by the geographical features of the catchment. This paper present an alternative to the large scale hydrological mathematical model based on offline and recursive/online parameter estimation of data-driven linear and nonlinear models. The updating of the model parameters allows to handle the variations due to the past rainfall quantities and to the weather forecasting.

When faults occur on sensors, corrupted data can be considered as correct, leading to undesirable management actions. Therefore, it is necessary to detect and localize these faults. In this paper, the detection and localization of sensor faults is performed through the analysis of the parameters of a grey-box model, which are obtained from available real data. The parameters are determined with a sliding window, with the exception of the delays, which are considered known a priori. A fault is detected and then localized when there is a change in the value of the parameters. This approach is well suited for constant faults and particularly well adapted for intermittent faults. Data of an inland navigation reach located in the north of France are used to highlight the performance of the proposed approach.

As example, in north of France, a shift of 20% from road transport to these alternative transport solutions is expected by 2050. Reaching this goal requires not only the delivery of new infrastructures and equipment, but also the design of efficient management strategies. By focusing on waterborne transport, it is thus necessary to improve the management of the inland navigation networks particularly the water resource. Indeed, the waterborne transport accommodation is strongly linked to the available water resource. This will be a challenging point in a global change context. The paper deals with the global change impacts on inland navigation networks. It aims at proposing new contributions as compared to past and current results of European projects on climate change and inland navigation. It appeared that the multiscale modeling approach for inland navigation networks that was proposed during the last TRA Conference in Paris in 2014 is useful to determine the resilience of these networks and their ability to guarantee the navigation conditions during drought and flood periods. The proposed tools are developed to consider two space and time scales. The first approach is used to determine the water quantity that is necessary to accommodate the navigation during half a day, and the second allows the efficient control of the gates to keep the water level of each navigation reach close to its setpoint by rejecting disturbances and compensating the waves due to the lock operations. One example based on the real inland navigation network of the north of France is used to highlight the contributions of the multi-scale modeling approach.
