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.

Automatic control

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); -- LQR controller design; -- 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.

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.

Duration of the exam is 2 hours. Allowed material: tables of Laplace transforms, single A4 sheet with formulas. Matlab programs, printed lecture notes and exercise solutions are not allowed. The students can upload only files created on vLAIB virtual machine during the exam. The exam is organized as a computer-based tests with 4-5 multiple choice questions (for their solution, Matlab functions can be useful) and 2-3 exercises on controller design in Matlab (the solution is a Matlab m-function). The students use virtual LAIB integrated with the university Exam platform. The multiple choice questions give about 24 points, covering the main topics of the course, in particular, derivation of dynamical equations, state-space models and their linearizations; Laplace transforms and transfer functions; modal analysis, stability analysis in the time domain (eigenvalues) and frequency domain (Nyquist); reponse to harmonic and polynomial inputs, disturbance rejection; controllability and observability; discretization. The design exercises give another 8 points and test a student's capability of designing controllers and observers that satisfy predefined specification by using pole placement and LQR methods. The answer to the design problem should be a Matlab script, returning the coefficients of a controller and/or observer. The examples of controller design will be considered during LAB sessions. The minimal grade needed to pass the exam is 18/30.
