Learning outcomes
The aim of this course is to give the students the background and fundamental principles of automatic control systems behaviour, examining both open and close loop configurations. During the course basic tools and techniques are introduced in order to perform:
- analysis of linear stationary dynamic Single Input / Single Output (SISO) system characteristics and properties
- synthesis of feedback control systems
- utilization of main components (actuators and sensors) in control loops.

Assessment methods
There is a two day exam: a written exam the first day, where the student is asked to deal with a multi question exercise to solve analysis and design problems about a control system. Each question has a predefined score. The written exam is passed if the total score is not below 15. The second part of the test is oral; it is obligatory if the written exit is between 15 and 17, optional if greater than 17. The oral exam has to be stood by the date of the oral test of the next examination session in order to improve or not the score of the written test. The final score if no optional oral test has been chosen is not greater than 24. The oral test consists on questions about theory of automatic control systems on which the student has to demonstrate a sufficient knowledge.
