Signal and Systems
3 ECTS
Aim:The objective of these notes is to give an accessible introduction to signals and systems for electrical engineering, computer engineering, and computer science.
Content:
- Fundamentals of continuous-time/discrete-time signals: (a) Introduction to Fourier and Laplace transforms; (b) theory of convolution and the concept of transfer function; (c) sampling and reconstruction
- Essentials of feedback control: (a) representation of dynamical systems (state-space, input-output); (b) basic feedback loops and more abstract representations; (b) structural properties (controllability, observability); (c) stability (internal, input-output) and sensitivity (load disturbance, noise); (d) control algorithms and methodologies (PID, state feedback, pole placement, observers)
- Dealing with uncertainty and systems’ limitations (measurement noise, actuator saturation, process dynamics)
