OVERVIEW

The course presents the basic notions and concepts related to the analysis and control of dynamic systems.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the main knowledge about dynamical systems, their different representations, their properties and the concept of feedback.

AIMS AND LEARNING OUTCOMES

The learning outcomes of the course refer to the capacity of

• understanding the main features of the system dynamics;
• knowing the formal representations of continuous-time linear time-invariant dynamic systems
• knowing the structural properties of continuous-time linear time-invariant dynamic systems, with main focus on stability properties
• analyzing several stability properties of a given system;
• verifying structural properties (reachability, observability) of a given system;
• designing stabilizing actions possibly also aimed at improving the dynamics of continuous-time linear time-invariant systems, by means of algebraic feedback.
