Control System Analysis and Design

CFU: 12
Lingua: Italiano
Descrizione dell'insegnamento
The course offers undergraduate students a rather broad view on Automatic Control methodologies and techniques for feedback linear systems.
Prerequisiti
Calculus 2
Scopi
It starts from the modeling problem using Laplace domain transfer functions and time domain State Variables, then shows the techniques to gain an inside view to the system structure (Kalman decomposition) and stability and to analyze the system performances both at steady state and during transients. Basic design technics are then introduced and finally the methodologies for the implementation of a control devices by a computer (i.e. as a discrete-time system) is presented.
