Description ​

  • Objectives: This module deals with the interface between a digital system (microprocessor, calculator, computer, etc.) and an electromechanical system (servo system, robot, electric vehicle, wind turbine, etc.). We are interested on the one hand in actuation (the motors) and on the other hand in feedback (the sensors). The objectives of this module are threefold:

    • Study the different motor technologies used in mechatronics, and their control principle.
    • Addressing Embedded Systems Power Issues
    • Acquire a general knowledge of instrumentation in order to be able to design and dimension an acquisition chain, from the sensor to the processing unit.

  • Teaching mode: This module consists of:

    • An instrumentation course presenting the instrumentation chain from the sensor to the analog-to-digital converter (sensor technology, conditioning, amplification, filtering, conversion).
    • A course on actuators (polyphase motors).
    • a course on electronic power supplies (linear or switching power supply),
    • An instrumentation project during which students must completely create an electronic card, the embedded code and an HMI to visualize the experimentally acquired data and compare them to the theoretical models seen in previous semesters (whether models seen in dynamics, in thermal or materials). In this project, students are grouped into groups of 5 (by random drawing) on ​​5 different subjects.
    • A mini-project (in pairs) on vector control of synchronous machines.

Learning Outcomes AAv (AAv) ​

  • AAv1 [heures: 5, C1] : Functional diagram and division into tasks of the project. At the end of this course, the seventh semester student will be able, in a group of 4 to 5 students, to produce a functional diagram and a forecast division of the necessary work into elementary tasks, for the realization of a project. instrumentation based on a microcontroller.

  • AAv2 [heures: 16, B1, C2, C3, D1, D3, D4, G2] : Electronic CAD. At the end of this course, the seventh semester student will be able, in a group of 4 to 5 students, to design, assemble, test and validate a functional double-sided electronic card (without metallized hole).

  • AAv3 [heures: 26, B1, C2, C3, D1, D3, D4] : Autonomous implementation of a microcontroller for an instrumentation application. At the end of this course, the seventh semester student will be able, in a group of 4 to 5 students, to implement a digital system allowing the instrumentation of a physical system (for example a motor, heating, pendulum, actuator shape memory alloy ...).

  • AAv4 [heures: 26, B2, B3] : General knowledge of instrumentation. At the end of this course, the seventh semester student will have a general knowledge of instrumentation.

  • AAv5 [heures: 12, B2, B3, B4, D3] : Comparison of experimental results with theoretical calculations or simulations. At the end of this course, the seventh semester student will be able, in a group of 4 to 5 students, to make the link between experimental data that they have produced and theoretical results obtained by calculation and/or numerical simulation.

  • AAv6 [heures: 5, E3, E4] : Group work in an unselected group. At the end of this teaching, the students of the seventh semester will be able to demonstrate their ability to work in a group that was imposed on them by drawing lots.

  • AAv7 [heures: 5, F1, F2] : Written summary (in a format of your choice, but of a limited size). At the end of this course, the seventh semester student will be able, in a group of 4 to 5 students, to produce a summary document presenting the measurement system that they designed, created and tested. The type of document is free: scientific article, poster, website, video mixing film and text plate. The only constraint is that the document must be concise and present only the points marking their achievement.

  • AAv8 [heures: 5, F1, F2] : Oral summary in group. At the end of this course, students in the seventh semester will be able to synthesize orally in a short time (10 minutes) the measurement system that they designed, created and tested.

  • AAv9 [heures: 13, B3, B4, D2, D3, D4] : Modeling for the vector control of a synchronous motor. At the end of this course, the seventh semester student will be able, in pairs, to establish a model in order to implement the vector control of a synchronous motor, with current and speed controls. The development context will lead to mastery of rapid prototyping tools in order to switch from a simulated model to functional code for the target.

  • AAv10 [heures: 12, C1, C3, D1, D2, D3, D4] : Speed ​​variation. At the end of this course, the seventh semester student will be able, in pairs, to design a program allowing a speed variator to be controlled via a fieldbus in order to respect the different operating modes.
