Learning goals:

This course is designed to provide the students with engineering knowledge and skills to design experiments, analyse data and to identify and validate models of dynamical systems, as appearing in industrial process control and mechanical servo systems. The methods as introduced in the course are supported by excercises on simulation and real-life examples, employing appropriate and user-friendly software tools.

Computer use:

Computers are used in the exercice sessions and for performing the take-home exam.

Laboratory project(s):

Design content:

The course is finished with an oral examination that is based on an assignment to identify and validate models from an experimental laboratory setup.

Percentage of design:  25%
