Teaching method

Theoretical-practical classes: presentation of theoretical concepts, methodologies and techniques, and discussion of case studies.
Practical classes: execution of projects in automation and control, involving the components of specifications, design, solution development and implementation.

Evaluation method

The individual continuous assessment consists of carrying out two laboratory works (Lab#1 and Lab#2), and a final test or exam (TF), with a minimum attendance rate (Freq) of 67% for practical classes.
Final Grade = 30% * (Lab#1) + 30% * (Lab#2) + 30% * (TF) + 10% * (Freq)
Frequency: Final Grade >= 7.
Approval: Final Grade >= 9.5.
