Full textIn this thesis we have proposed two original identification approaches of a class of discrete event systems using Petri Nets. Our first proposed approach consists in using the output symbols of the target system to elaborate its behavioural model in PN form. The necessary and the sufficient conditions for the existence of a unique solution are established. Moreover, the identification problem is defined as a binary linear programming problem where the uniqueness of the solution is not guarantee. For our second method, it based on using the measurable input and output system signals. It consists in calculating the measurable part, estimating the non measurable one and developing different algorithms to estimate the structure and the initial marking of a PN model to be identified. However, the latter can generate, in some times, some behaviours which are not equivalent to those generated by the real system. These behaviours are considered as illegal. To inhibit the identified model to access to these illegal states two synthesis approaches of PN controller are proposed. Finally, the results obtained in this thesis have been validated on a real system

Full textThe growth of renewable energy production is changing the future of power transmission systems. In recent years, High-Voltage Direct Current (HVDC) technologies based on Modular Multilevel Converters (MMC) are embraced by industry and academia as a solution for the efficient integration of renewable energies into electrical grids. However, this type of technology introduces new challenges in the way power transmission systems are controlled and operated, as faster and more complex control strategies will be needed in a domain which nowadays relies heavily on human decision. In this context, Discrete Event Systems (DES) modeling and Supervisory Control Theory (SCT) are powerful tools for the synthesis of supervisors ensuring that the system to be controlled respects a set of behavioral specifications, imposed by the designer, within its physical limitations. This work proposes a method for the full development, from conception to implementation, of the supervisory control of a multi-terminal DC (MTDC) system. A functional analysis on the considered system has been done so as to identify the main components and operational modes of the grid. Then, the proposed solution is based on the discrete-event modeling of the continuous-time behavior of the components in the system. From there, SCT concepts are applied so as to obtain a hierarchical control architecture taking into account the priority of some control actions that should be treated at the local level. Furthermore, the obtained discrete controllers present a mode-switching structure in order to realize mode management during the operation of the MTDC grid. Finally, a method for the implementation of the obtained controllers in widespread power system simulation software is proposed. The whole work has been validated through the simulation of a case study, involving the mode management of a 3-terminal bipolar MTDC system

Full textDans la première idée, nous avons utilisé le théorème introduit par Guia, qui permet de passer d'un ensemble d'états interdits vers un ensemble de contraintes linéaires. Nous avons proposé des méthodes originales de simplification des contraintes. Il est alors possible de réduire le nombre et la borne des contraintes et ainsi de construire un modèle contrôlé simple. Les méthodes de simplification présentées sont applicables sur les RdP saufs. Nous avons déterminé les conditions nécessaires et suffisantes pour avoir un contrôleur maximal permissif. L'avantage principal de ces méthodes de synthèse de contrôleurs est que le modèle RdP contrôlé est très proche du modèle initial.
La deuxième idée qui a été utilisée pour la synthèse est l'utilisation des conditions pour le franchissement des transitions contrôlables. Les méthodes qui utilisent cette technique, ont en général besoin d'un calcul long en temps réel. En appliquant notre méthode de simplification, nous arrivons à un contrôleur simple.

Full textIn this work, we propose a systematic method for controller synthesis in discrete events systems. We model the process and the specification by safe Petri Nets (PN). Two distinct ideas are used: 1) adding the control places to prevent the reachability of forbidden states, and 2) adding conditions with the controllable transitions. The uncontrollability asks the problem of optimatlity and the large number of control places the problem of complexity. In the first idea, we use the theorem introduced by Guia, which makes it possible to pass from the set of forbidden states to the set of linear constraints. We propose original methods of simplification of the constraints. It is then possible to reduce the number and the bound of the constraints and thus to build a simple controller model. The methods of simplification presented are applicable on safe PN. We determine the necessary and sufficient conditions to have a maximal permissive controller. The principal advantage of these methods is that the controlled PN model is very close to the PN initial model. The second idea for controller synthesis is the using of conditions for controllable transitions. The methods which use this technique generally need a long calculation in real time. While applying our method of simplification, we arrive to a simple controller

Full textThe research results presented in this thesis falls within the framework of control reconfiguration of Automated Production Systems (APS) seen as a class of Discrete Event Systems (DES). The reconfiguration is based on Supervisory control theory (SCT) and triggered following a plant fault detection (fault tolerant control). The faults considered in this report are sensor faults (a sensor which remains blocked on reading 1 or on reading 0). The main contribution is based on a safe control synthesis founded on timed properties. In fact, if a sensor fault is detected, the controller of the normal behavior is reconfigured to a timed one where the timed information compensates the information lost on the faulty sensor. The switch between normal and reconfigured behaviors is ensured using reconfiguration rules. The main objective of our method is to implement the obtained control into a PLC. To meet the different objectives, we propose a method to translate the distributed controllers of the two operating modes, as well as the reconfiguration rules into different Grafcets implantable in a PLC. The implementation of these different models is verified by a model-checking technique before being tested on a digital twin. Finally, we apply our contribution to a real system to illustrate our results
