OVERVIEW

"Automatica" is the discipline that deals with methods and technologies for information processing aimed at (real time) automatic control of plants, processes and dynamic systems in general. Typical applications embrace different areas of engineering and science. An objective of particular importance in the field of "Automatica" is the design of closed loop regulators granting stability and satisfaction of appropriate performance specifications.

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.

SYLLABUS/CONTENT

The contents 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) 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.
