### Teaching description

Sufficiency in calculus, linear algebra, systems and signals, systems theory.

This course offers a broad overview of fundamental and emerging topics in the area of control and systems theory. Applications are illustrated in the fields of robotics, multi-agent systems and cyber-physical systems. It is aimed at providing principles and tools to state and solve optimal control problems eventually seeking distributed control architectures in several technological systems, and the solution is sought both analitically through direct computation and also numerically with the aid of a suitable software (Mathworks Matlab is used in the course).

Learning Outcomes; after the course the student should be able to:

(Conoscenze e comprensione) Describe and explain the main peculiarities (both advantages and disadvantages) of the classical and modern control theory considered in the course.

(Capacità di applicare conoscenze e comprensione)+ (Abilità comunicative) + (Autonomia di giudizio) Be aware of, describe and explain practical problems of controlling complex systems, and how to overcome these drawbacks using modern approaches.

(Capacità di applicare conoscenze e comprensione)+ (Capacità di apprendimento) For a given practical problem at hand, the student should be able to state a control problem in a natural mathematical setting, eventually seeking distributed architectures, based on the problem assumptions.

(Capacità di applicare conoscenze e comprensione) +(Abilità comunicative) + (Autonomia di giudizio) Starting from a theoretical formulation of a problem, the student should be able to build a simulation framework to find a computer-aided solution of the stated mathematical problem with the use of a suitable software.

(Abilità comunicative)+(Capacità di apprendimento) Willing students may develop a project on an application of interest where to apply the methodologies developed along the course.

Lezioni frontali svolte in aula dal docente tramite l'ausilio di gesso e lavagna. Nel corso delle lezioni saranno occasionalmente illustrati e discussi  software commerciali.

The exam is a written exam and an oral discussion, and it is aimed to determine to what extent the student has: 1) the ability to identify and use data to formulate responses to well-defined problems, 2) problem solving abilities to seek an analytical solution. Additionally, willing students may have a seminar or a project on an application of interest where the methodologies of the course are applied.
