Objectives

General objectives

The course focuses on the analysis and control of dynamic systems, with particular reference to linear time-invariant systems.

Specific objectives

Knowledge and understanding:
Students will learn the basic methods for the analysis and control of linear time-invariant systems. In particular, students will learn how to characterize a system to be controlled, from the point of view of structural characteristics, and which possible methods can be used for the design of controllers.

Apply knowledge and understanding:
Students will be able to design controllers that ensure the satisfaction of specifications concerning the stability, tracking and rejection of disturbances using frequency domain and eigenvalue assignment methodologies.

Critical and judgment skills:
The student will be able to choose the most suitable control methodology for a specific system based on the control specifications.

Communication skills:
The course activities allow the student to be able to communicate / share the main problems concerning time-invariant linear systems and the possible design choices for the control of such systems.

Learning ability:
The aim of the course is to make students aware on how to deal with analysis and control problems in the context of automatic controls.

Bibliography

Other bibliographic references are not indispensable.

Prerequisites

Prerequisites: Basic knowledge of mathematical analysis. Basic knowledge of geometry. There are no prerequisite exams.

Study modes

The course is taught by using the blackboard and/or slides depending on the topic. If it is not possible to carry out the lessons in the classroom with all the students due to the pandemic, the lessons are carried out in mixed mode (in the classroom with streaming for students who use remotely) or exclusively in streaming if no student can attend. The instructions are indicated on the course page (https://sites.google.com/a/dis.uniroma1.it/antonio-pietrabissa/teaching/fondamenti-di-automatica)

Frequency modes

In presence and online (link on the course site https://sites.google.com/a/dis.uniroma1.it/antonio-pietrabissa/teaching/)

Exam modes

The written test consists of one or two exercises on control methods in the Laplace domain, one exercise on control methods in the time domain and/or some open-ended questions on the course programme. Indicatively, each exercise or set of questions accounts for one third of the evaluation.
The oral test consists of the written test discussion with possible insights. The final grade will take into account the written grade and the evaluation of the answers to the questions of the oral exam.
