Expected results according to the Dublin descriptors.
- Knowledge and ability to understand: the student must be able to analyze industrial control systems and PID controllers.
- Ability to apply knowledge and understanding: Evaluation of control systems performance. Use of software packages (MATLAB, OCTAVE...) to evaluate control systems performance.
- Making judgments: develop the ability to critically assess the behavior of a closed-loop control system.
- Communication skills: ability to clearly express procedures and results regarding closed-loop control systems.
- Ability to learn: know how to integrate knowledge from various sources in order to achieve a broad vision of the problems related to the behavior of closed-loop control systems.

The exam is divided into a written test, a homework exercise and an oral test. The written test consists of two numerical exercises with an assigned score. The written test is intended to be passed with a minimum score of 16. The homework exercise consists of the design of a control system using Matlab. In the oral exam, which can be performed on the same day or after a few days, the ability to link and compare different aspects treated during the course is evaluated. The final score is calculated as an average of the score of the written exam and the score of the oral exam. Up to 5 points are assigned to the homework.
Lectures are in Italian. The professor is fluent in English and is available to interact with students in English, also during the examination.
