The course provides the basics for the study of the dynamics of mechanical systems with linear models and of the synthesis of control systems.
The course aims to: provide the tools for the study of the dynamics of mechanical systems by means of linear models, with single input and single output, introducing the concepts of open-loop and closed-loop systems; teach the criteria for the evaluation of servo systems and their control; present the basics of analog, digital and mixed automation systems.
Theoretical lessons integrated with examples and exercises. The students can extend the exercitations by means of MatLab.
