Lecturer

Prerequisites
Knowledge of Signals and Systems and of Laplace transform.

Objectives
This module aims to provide knowledge of several automatic control systems structures, to develop competences in the design of classical control systems using time invariant linear continuous systems and to analyse stability and performance.

Program
Introd. to control systems. Time-domain analysis, in open and closed loop: transient response, steady state error, stability (Routh/Nyquist). Controller design, analysis of control systems based on root locus, frequency design, Bode Diagram. Stability criterion.
PID control: methods of Ziegler-Nichols, pole-placement, etc. Techniques of project and compensation. Disturbances and Delay. Digital PID

Evaluation Methodology
Written open-book examination during regular examination seasons(75%) and Practical assignments (25%).

Method of interaction
Lectures expositive and demonstrative where the study methods are described and exemplified; theoretical-practical and laboratory-practices lessons where applicationexercises are solved and where laboratory experiments are implemented.
