Subject fundamentals
Obiective of the course is to provide the students with the fundamentals of control systems, with emphasis to the systems controlling a mechanical quantity (position, velocity, force, pressure, etc.). The course includes the presentation of working examples relevant to several industrial applications.

Expected learning outcomes
It is expected that the students will gain a knowledge of the general characteristics of control systems together with the ability to apply the most common techniques of systems modeling and to describe the systems components with first and second order linear models. The students will acquire a competence on the main techniques used in systems control and a knowledge of the most common types of actuation systems and servomechanisms.

Prerequisites / Assumed knowledge
It is mandatory for the students to have a knowledge of theoretical and applied mechanics, mechanical drives and the basics of calculus.
