Description
The objective of this unit is learning the concept of discrete time dynamic system, including the control design.
There are several derives concepts, namely:
- what is a discrete system, how is characterized and what mathematical representations admits;
- differences between continuous and discrete signals;
- stability and performance;
- discrete time domain and complex frequency domain;
- feedback and closed loop stability;
- application limits of digital control;
- state-space representation;
the student should also know how to:
- convert a continuos system in its discrete equivalent;
- identify the poles and zeros of the transfer function and estimate the performance/stability from its pole-zero diagram;
- plot and analyse Bode and Nyquist diagrams;
- conclude about the stability of a closed loop system from its open loop Bode and Nyquist diagrams;
- compute the eigenvalues of the state-space representation and conclude about the stability;
- design a state variables feedback controller;
additionally, the student acquires the following non-technical competences:
- make a report on experimental work;
- manage time and meet deadlines;
- collaborative team work; abstract and formal reasoning;
- abstract modelling of problems; sub-optimal solutions;
