Teoria de Controlo

The student attending these classes with success should understand the following concepts:
- What is a system, how is characterized and what mathematical representations admits;
- Functional scheme of a system;
- Stability and performance;
- Time and complex frequency domain;
- Frequency response; minimum and non-minimum phase.
- Feedback and closed loop stability;
- What is control and their application limits;
additionnaly, the student should know:
- Model a physical process using diffrential equations and convert them to transfer functions; Compute the free and forced response;
- Identify the poles and zeros of the transfer function and estimate the performance/stability from its pole-zero diagram;
- Plot the closed-loop root-locus diagram;
- Plot the Bode and Nyquist diagrams;
- Conclude about the stability of a closed loop system from its open loop Bode and Nyquist diagrams (including gain and phase margins);
- Design a PID controller using the Ziegler-Nichols rules;
- Compute the descritive function of a static non-linearity;
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;
