OVERVIEW

"Automatica" is the discipline that deals with information processing methods and technologies aimed at the automatic and real-time control of plants, processes, and dynamic systems in general, with applications spanning different areas of engineering and science. A particularly important goal of "Automatica"  is the design of closed-loop controllers granting stability and fulfillment of desired performance specifications. In the naval field, applications of  "automatica" include the control of propulsion systems, of individual equipment and on-board processes, and course and navigation control systems, to name but a few examples. The concepts and methods developed in the course are the fundamental tools for understanding the role of automation systems applied to marine engineering.

AIMS AND CONTENT

LEARNING OUTCOMES

Provide the students with the capability to design closed-loop regulators and apply such a capability to plants of interest in ship automation.

AIMS AND LEARNING OUTCOMES

At the end of course the student must

  1. know the linear time-invariant (LTI) systems and their representation by means of state equations and transfer functions;
  2. use the Laplace transform and block diagrams;
  3. perform the frequency analysis of LTI systems with single input and single output (SISO);
  4. know the structural properties of a dynamic system (stability, controllability, and observabilty);
  5. analyze the stability of LTI SISO systems under feedback by means of the Nyquist and Bode criteria;
  6. design closed-loop regulators for LTI SISO systems;
  7. analyze the effect of disturbances and model uncertainties in closed loop.

PREREQUISITES

Linear algebra and calculus.

TEACHING METHODS

Lectures of theory and exercises for a total of 60 hours. Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the professor of the course and with the Polytechnic School - Engineering's disability liaison (https://unige.it/en/commissioni/comitatoperlinclusionedeglistudenticondisabilita).

SYLLABUS/CONTENT

The contents of the course may be summarized as follows: 1) linear time-invariant (LTI) systems and their representation by means of state equations and transfer functions; 2)  Laplace transform and block diagrams; 3)  frequency analysis; 4) introduction to structural properties of a dynamic system (stability, controllability, and observabilty); 5) stability of LTI SISO systems under feedback by means of the Nyquist and Bode criteria; 6) design of closed-loop regulators for LTI SISO systems; 7) analysis of the effect of disturbances and model uncertainties in closed loop.
