Expected results according to the Dublin descriptors.
- Knowledge and ability to understand: the student must be able to analyze linear systems and understand the specifications of a control system.
- Ability to apply knowledge and understanding: Design of PID controllers using MATLAB-SIMULINK.
- Making judgments: develop the ability to critically assess the closed-loop behavior of a control system.
- Communication skills: ability to clearly express procedures and results regarding system analysis and standard controller design.
- Ability to learn: know how to integrate knowledge from various sources in order to achieve a broad vision of the problems related to the closed-loop behavior of control systems.

The exam is divided into a written test and an oral test. The written test consists of three numerical exercises with an assigned score. The written test is intended to be passed with a minimum score of 16. 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.
Lectures are in Italian. The professor is fluent in English and is available to interact with students in English, also during the examination.
