Objectives and content#

Mechatronic and space systems are highly complex systems that often have to meet specific and stringent requirements depending on the application. They require the joint development of technological systems and control software. This course provides an introduction to the concepts and development of such systems:

  • Requirements analysis and preliminary design

  • Dynamic modeling and identification of multiphysics technological systems.

  • PID control and digital implementation.

Case studies#

This course will take as case studies the thermal and attitude control of Cubesats. For pedagogical reasons, the approaches will be deliberately simplified, and the digital implementation of the correctors will be done on Arduino boards.
