PRESENTAZIONE

Systems' Theory is one of the first discipline where mathematical and real aspects of engineering meet. Different skills are integrated to build and analyze mathematical models representing actual systems, in order to understand, foresee and control their behaviour.

OBIETTIVI E CONTENUTI

OBIETTIVI FORMATIVI

The teaching unit aims to provide students with the theoretical and methodological tools for modelling, analysing, and controlling linear dynamic systems.
The topics covered are presented to students in a way that helps them become familiar with essential tools from mathematics and geometry needed for systems modelling and control.

OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO

The course aims to provide the students with the necessary methods to analyze mathematical models for dynamic systems. 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 and discrete-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;

-        designing a state observer in case the system state is not accessible.

PREREQUISITI

The student must have adequate knowledge of Mathematics, Physics, and Geometry.

MODALITA' DIDATTICHE

The course offers classroom lessons that cover detailed methods for analyzing and controlling dynamic systems, including numerical examples also using the Matlab software environment.

Depending on particular weather alerts, lessons may be taught in blended modality and/or with the availability of video lessons.

Gli studenti con certificazioni valide per Disturbi Specifici dell’Apprendimento (DSA), per disabilità o altri bisogni educativi sono invitati a contattare il docente e il referente di Scuola per la disabilità all’inizio dell’insegnamento per concordare eventuali modalità didattiche che, nel rispetto degli obiettivi dell’insegnamento, tengano conto delle modalità di apprendimento individuali.

I contatti del referente di Scuola per la disabilità sono disponibili al seguente link https://unige.it/commissioni/comitatoperlinclusionedeglistudenticondisabilita.

ESAMI

MODALITA' D'ESAME

The student must undergo a compulsory written examination. An additional oral exam can be done, but it is not mandatory. During the exam the student has to solve numerical exercises and to explain the theoretical notions necessary for their solution

MODALITA' DI ACCERTAMENTO

The exam aims to assess the following aspects of the student’s preparation:

• the ability to analyze the structural and behavioural characteristics of linear time-invariant dynamic systems;
• the ability to design actions to improve the dynamic behaviour of the system under consideration;
• the ability to design state observation techniques for a linear dynamic system.

The exam assessment will take into account not only knowledge of the course contents, but also calculation skills and logical reasoning abilities in solving numerical examples.

ALTRE INFORMAZIONI

Gli studenti con certificazioni valide per Disturbi Specifici dell’Apprendimento (DSA) possono richiedere adattamenti in sede d'esame, con almeno 7 giorni di anticipo rispetto alla data dell’esame, compilando il "modulo richieste adattamenti" (dai servizi online https://modulionline.unige.it/richiesta-adattamenti#no-back) che verrà inviato in automatico dal sistema al/alla docente responsabile dell’insegnamento e al/alla docente referente per gli studenti con disabilità e con DSA della propria Scuola/Area.

Lo studente riceverà una copia della sua richiesta.
