Digital Control Systems ( 5 CFU ) Finalità

The course is designed to give the fundamentals of control theory based on digital systems with sampled data. Discrete systems are analysed and the main digital feedback-based control techniques are studied. The theoretical program is completed by laboratory lectures.

Programma

a)Discretization-based design: backward transform, forward transform, bilinear transform, matched pole-zero method, impulse response invariance and step response invariance methods.

b)Analytical design: Diophantine equation, unitary feedback controller through the Diophantine equation, deadbeat and modified deadbeat methods.

c)Standard discrete regulators: PID-controllers and their tuning, effects of signal saturation, forward compensation.

Attività d'esercitazione

The course includes some laboratory lectures in which the discrete systems analysis techniques are applied and some of the regulators proposed in the theoretical lectures are simulated. The programs used are Matlab and Simulink.

Modalità d'esame

The exam is written and is divided into two parts, the first part includes some exercises, the second some theoretical questions. A couple of mid-term tests are scheduled during the class period.
