The subject provides an introduction to the basic/intermediate principles and tools for the design and analysis of feedback systems, many of which, in daily use are relatively complex ones, including mechanical, electronic, computer hardware/software and possibly other components as well. Systems engineers study the whole rather than one particular component, through mathematical modeling, design, analysis and implementation in order to get the fulfillment of given requirements. Further topics include: (a) quantitative models of mechanical, electrical and electronic physical systems, described by linear, ordinary differential equations; (b) stability, steady state and transient performance analysis of single input, single output open loop and closed control systems; (c) steady-state and transient requirements translation; (d) frequency domain controllers design through phase-lead and phase lag networks.
We have attempted to keep the mathematical prerequisites to a minimum while being careful not to sacrifice rigor in the process. We have also attempted to make use of examples from a variety of disciplines, illustrating the generality of the introduced methods and tools.
A major goal of this course is to present a concise and insightful view of the current knowledge in feedback and control systems.
Summarizing, the objective of this course is to apply knowledge of mathematics and engineering to analyze and design a control system to meet desired specifications.

Theoretical and methodological lessons are delivered, on a weekly scheduled basis, by face-to-face instruction in the classroom. Computer laboratory activities are scheduled in order to develop the student’s skill through proper training. Each student is supposed to practice individually with the aid of laboratory work stations. The primary purpose of the laboratory exercises is to apply the methodologies presented in class, through the use of MATLAB, Simulink and the Control System Toolbox. Some exam simulations are presented in the last two weeks of the course.

Written examination in computer laboratory: based on computer aided analysis and design of a feedback control system, adequately documented through a written report. More precisely, it is required to (A) Understand and translate the design specifications (12 - 16 points); (B) Design a controller that guarantees fulfillment of the assigned requirements (6 - 8 points); (C) Report the obtained performance of the designed feedback control system (5 - 7 points); (D) Carry out further performance analysis of the designed control system against given disturbances (5 - 7 points); (E) Provide orderly and clear presentation with legible handwriting (2 points). During the examination, lasting 4 hours, the student may consult the lecture slides provided by the lecturer. Detailed instructions and rules are presented in due course.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
