Lectures will be concerned with theoretical topics, numerical examples and solved problems. LAB exercises will also be carried out, based on the Matlab/Simulink software. The LAB sessions will be focused on the development of academic and applicative examples, some of which are taken from the automotive field.
The course consists of lectures and laboratory practicums. Lectures cover -- the theoretical topics of the course (the concepts of dynamical systems, state-space models, linear stability analysis and design of stabilizing controllers, frequency-domain techniques for linear systems, basics of identification, PID controllers); -- some numerical examples and solved problems; -- seminar-style lectures on automotive applications. In the case of mixed online-offline teaching, the theoretical material will be primarily taught online. The offline lectures will be devoted to consideration of examples and problems (the materials will also be available online). The goal of LAB sessions is to enable students to use MATLAB and Simulink software for numerical simulation, rigorous analysis and design of control systems. The solutions to all problems will be available on the course webpage. The topics of the exercises are: -- derivation and linearization of mathematical equations (state-space models), linearization; -- implementation of models in Simulink, analysis of input-output response; -- analytic and numerical stability analysis; -- transfer functions, Laplace transforms, response to harmonic signals; -- minimal state-space realizations, observability, controllability; -- Nyquist criterion, frequency-domain analysis (stability margins); -- Design of controllers satisfying certain specifications (rise time, overshoots); -- Optimal controller design (linear-quadratic regulators); -- Observer design. In the case of online teaching, the students can either use virtual LAIB (vLAIB) with preinstalled software or download Matlab with Campus licence to their home computers.

Modalitą di esame: Test informatizzato in laboratorio;
Exam: Computer lab-based test;
The total duration of exam is 3 hours. The computer-based test includes 6 (six) multiple-choice questions with 3-5 alternatives and 1 (one) design exercise. During the exam, you can use only a table of Laplace transforms. You cannot bring any other printed or handwritten materials. You are not allowed to bring any programs on USB sticks and use any electronic devices except for the laboratory computer (Matlab and Simulink will be installed on it). Each multiple-choice question gives 4 points if answered correctly and 0 points if skipped or answered incorrectly. The questions can be fully theoretical (e.g. what is an observable system?) or require to solve a simple problem (e.g. to find the poles of a given transfer function or to solve a linear time-invariant system using Laplace transforms). The design exercise requires to write and submit a Matlab M-function (potentially, accompanied with a Simulink diagram) that finds the controller and observer with a set of predefined properties and illustrates the behavior of the closed-loop system. The design exercise gives up to 7 points (partial grading applies). The final mark is computed as the sum of points collected for all tasks. Mark 31 corresponds to 30L.
Gli studenti e le studentesse con disabilitą 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'Unitą Special Needs, al fine di permettere al/la docente la declinazione pił 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.
Modalitą di esame: Prova scritta tramite l'utilizzo di vLAIB e piattaforma di ateneo;
Computer-based test with multiple-choice questions and design exercises. Some tasks may require to use Matlab, which is available either on laboratory (LAIB) computers or, in the case of online exam, through the virtual LAIB (vLAIB) environment. Duration of the exam: 2 hours. Allowed material: tables of Laplace transforms, single A4 sheet with formulas. Matlab programs, printed lecture notes and exercise solutions are not allowed.
Exam: Written test via vLAIB using the PoliTo platform;
The total duration of exam is 3 hours. The computer-based test includes 6 (six) multiple-choice questions with 3-5 alternatives and 1 (one) design exercise. During the exam, you can use only a table of Laplace transforms. You cannot use any other materials and any electronic devices except for the computer used to take the exam. Please keep it in mind that the computer has to be equipped with camera (to provide video-surveillance during the exam). All programs (Matlab etc.) and files can be opened only on the VLAIB virtual machine. Detailed instructions will be provided. Each multiple-choice question gives 4 points if answered correctly and 0 points if skipped or answered incorrectly. The questions can be fully theoretical (e.g. what is an observable system?) or require to solve a simple problem (e.g. to find the poles of a given transfer function or to solve a linear time-invariant system using Laplace transforms).
