Internship Modelling of non-linear excentre mechanism

Apply now

Demcon is a company that develops a variety of new high-tech mechatronic systems. Many of these systems require some type of controller design to put all hardware in motion and meet system requirements.  Often, PID-type controllers are tuned in de frequency domain to control linear plants. Robust stability margins are taken to deal with dynamic variations.  Prior to the controller design the system is modelled to understand dynamics and identify controllability.


For nonlinear systems, controller design and modelling methods are often like those for linear systems. However, instead of evaluating the system in the entire range of the degrees of freedom, the system is linearized around certain configurations. With the help of Ansys motion, there is a new way to model and analyze non-linear systems. This happens in co-simulation with MATLAB/Simulink and is suitable for easier understanding of non-linear systems and flexible bodies.

About Demcon

Each one of our companies differentiates itself in its own domain with unique expertise and skills. This way they help customers improve their performance and achieve more. On the basis of their passion for technology our companies are able to combine forces. By sharing knowledge and working together we increase our social impact. Demcon is a developer and producer of technology and innovative products that contribute to solutions for technical and social problems.

What are you going to do?

This internship will focus on performing such a co-simulation on an excentre design. This excentre design faces non-linearities in mass and stiffness. A possible outline of this project could be: 

  • Understanding existing modelling methodologies
  • Co-simulation with Ansys-motion and MATLAB/Simulink 
  • Comparison to existing linear approaches 

What do you bring to the table?

Required pre-knowledge:

  • MSc education program in Mechanical Engineering, Electrical Engineering, Systems and Control or another relevant study with a strong background in control. Knowledge about Matlab/Simulink is required.

Note: application deadline 25 February 2024
