OVERVIEW

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.

AIMS AND CONTENT

LEARNING OUTCOMES

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.

AIMS AND LEARNING OUTCOMES

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.

PREREQUISITES

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

TEACHING METHODS

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.

Students who hold valid certificates relating to Specific Learning Difficulties (SLD), disabilities or other educational needs are invited to contact the lecturer and the school’s disability liaison officer at the start of the course to agree on any teaching arrangements which, whilst respecting the course objectives, take into account individual learning styles.

The contact details for the university’s disability liaison officer are available at the following link: https://unige.it/commissioni/comitatoperlinclusionedeglistudenticondisabilita.

RECOMMENDED READING/BIBLIOGRAPHY

All teaching materials will be available on Aulaweb. Generally, notes taken during lessons and the slides provided on Aulaweb are sufficient to meet the learning objectives.

Potential books for comprehensive analysis are the following:

• Rinaldi Piccardi: I sistemi lineari: teoria ed applicazioni. CLUP
• Bolzern, Scattolini, Schiavoni: Fondamenti di Controlli Automatici, McGraw Hill
• Antsaklis Michell: Linear Systems

EXAMS

EXAM DESCRIPTION

Oral examination. Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

ASSESSMENT METHODS

Analysis of the properties of a dynamic system. Starting from an exercise students are required to show theircomprehension about the behavior of dynamical systems and the characterizing  properties.

FURTHER INFORMATION

Students with valid certifications for Specific Learning Disorders (SLD) may request accommodations for exams at least 7 days prior to the exam date by filling out the “accommodation request form” (available via online services at https://modulionline.unige.it/richiesta-adattamenti# no-back), which will be automatically forwarded by the system to the instructor in charge of the course and to the faculty liaison for students with disabilities and SLDs in their School/Department.

The student will receive a copy of their request.
