Automatica is the discipline that is concerned with the structural proprieties of the dynamic systems, which are used to describe plants, process, and time-varying behaviors in many fields not only in engineering. A goal of particular importance is the design of closed-loop regulators with guarantee of stabilty.
Provide the students with the capability to design closed-loop regulators and apply such a capability to plants of interest in ship automation.
At the end of course the student must
Lectures of theory and exercises for about 60 hours.
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 state regulators for LTI SISO systems; 7) analysis of the effect of disturbances in closed loop.
