The course provides the basic notions for the analysis of control systems and for the tuning of PID controllers.
The course provides some of the skills required by the 2010 STCW International Convention to access the professional figures of Deck Officer and Engineer, implemented by the Ministerial Decree MIT 19 December 2016 "Training path to access the professional figures of Deck Officer and Engine Officer Student "as amended by MIT Ministerial Decree no. 35 of 10/10/2018.
In particular, the skills provided by the course include those specified in Annex II of the previous decree for Engineer Officer Pupils, namely:
C1. Control systems: characteristics and methodologies of the various automatic control systems (30h)
C2. Control systems: the proportional-integral-derivative control characteristics and the systems of the associated devices for process control (18h)
Further details relating to the skills acquired are provided in the extended program.
Frontal lectures; classroom exercises; lab sessions with MATLAB-SIMULINK.

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.
