Today, Internet makes possible remote access to PLC (Programmable Logic Controllers) remote maintenance, monitoring, supervision and follow-up of plants. In this article, we are interested in the possibilities that Internet offers for the D.E.S (Discrete Events System) teaching. The concept of distributed practical work room is proposed in order to(More)
In order to establish a method to synthesis controllers, an essential step is the modelling of both plant and constraints. However, this step remains a very complex task. To mitigate this difficulty and facilitate modelling, we present a methodology for plant modelling based on rules; as well as a user friendly methodology for constraints modelling based on(More)
Objectives of technical courses are knowledge and know-how transfer to students. In the case of Discrete Events Systems courses, it is important for learner to control locally or remotely real systems (or plants) composed of many sensors and actuators. The use of these devices poses several problems. Firstly, it is difficult to adapt them to the student’s(More)
Objectives of Automation courses are knowledge and know-how transfer to students. It is important for learner to control locally or remotely real systems composed of many sensors and actuators. The use of these devices poses several problems. Firstly, it is difficult to adapt them to the student’s level (from beginner to expert). Secondly, these(More)
We are interested in the remote use of automated systems by students within the framework of Discrete Event Systems teaching. One of the most important problems in this case, is to guarantee that the proposed PLC (Programmable Logic Controller) control is correct: in the other word, respecting the specifications given by the teacher. Hence, there is a(More)
The paper deals with an online safety mechanism to define interactions between a diagnoser and a control filter for fault tolerant control of manufacturing discrete systems. The diagnoser observes the plant behavior whereas the control filter ensures the safety from the controller. This online interaction is based by events communication where the control(More)
This paper deals with dynamic reconfiguration of DES control within the context of manufacturing system to answer product variability or production resources availability. More precisely, it focuses on productdriven control (PDC) that embeds decisional and adaptation capabilities within the product. PDC can be defined in a static or dynamic way: in the(More)
In this paper, we interest us to Human-Machine Systems (HMS) concepts applied to Education. It is shown how the HMS framework enables to propose original solution in matter of education in the field of control engineering. We focus on practical courses on control of manufacturing systems. The proposed solution is based on an original use of real and(More)
In order to improve the availability and reliability of manufacturing systems, the diagnosis method is primordial. The literature around the diagnosis of Discrete Event Systems (DES) have proposed different approaches and diagnosability assessment. This paper presents a local modelling of diagnoser and a diagnosability evaluation by Model-Checking. This(More)
