|SCIENTIFIC DISCIPLINARY SECTOR
Automatic control systems represent the fundamental technology for the construction of machines and systems, in all fields of engineering, capable of operating automatically with precision and reliability, without the direct intervention of human operators.
The automatic control systems are based on the concept of feedback and its properties. All systems, both natural (biological, social systems, etc.) and artificial (machines, devices, processes, etc.) perform their function on the basis of feedback mechanisms which, if properly managed, make their functioning effective.
The Automatic Controls subject provides the fundamental elements necessary to understand the operation and properties of feedback control systems and the basis for engineering control systems.
AIMS AND CONTENT
The course aims to provide the basic tools for the synthesis of regulators for continuous-time dynamical systems.
AIMS AND LEARNING OUTCOMES
This subject aims to provide students with: the fundamental concepts underlying the regulation and control of dynamic systems, the basic tools for analyzing the behavior of feedback control systems and for designing simple analog regulators.
At the end of the course, the student will be able to analyze the characteristics of stability, precision, noise rejection and robustness of linear time-invariant feedback systems with single controlled variable (LTI-SISO). It will also be able to synthesize the regulation function (regulator) for the control of simple LTI-SISO systems.
The technical tools of this subject are based on
- Fundamentals of Mathematical Analysis and Algebra of Complex Numbers
- Fundamentals of Systems Theory
Understanding the concepts presented in this subject requires at least a vague idea of how the world around the student works. For this purpose, at least an understanding of the basics of the following disciplines is considered useful
- Elementary physics (mechanics / electromagnetism)
- Electrical engineering / circuits
- Other basic engineering disciplines
Lectures to introduce the conceptual tools and exercises carried out in the classroom to apply the concepts to case studies and facilitate learning.
Attendance is recommended.
Furthermore, exercises and problems are proposed during the lessons, the development of which is the responsibility of the students. The teacher is constantly available to discuss the solutions proposed by the students.

L'orario di tutti gli insegnamenti è consultabile all'indirizzo EasyAcademy.
Written exam consisting in the solution of some simple exercises followed by questions (multiple choice quizzes) relating to the exercises carried out in the first part of the exam.
Students with specific learning disabilities (DSA) will be allowed to adopt specific methods and supports that will be established on a case-by-case basis in agreement with the Delegate of the Engineering courses in the Commission for the inclusion of students with disabilities.
The learning outcomes are assessed by means of the exam described in the section "exam methods".
The educational objectives are considered achieved to the extent that the student:
