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
Students will be assessed individually for each assessment element, although practical work can be carried out in groups.
The evaluation elements will be the following, considering each grade in the range [0;1]:
- Lab work TP#1, with final oral assessment of work and PDF report;
- Lab work TP#2, with final oral assessment of work and PDF report;
- Test or Final Exam (TEF).
TxFreq: Rate of attendance of practical classes.
To obtain frequency, each student must obtain a grade equal to or greater than 7.0 in the test and in the Labworks, and ensure that their TxFreq > 67%.
To obtain approval, each student must obtain a final grade equal to or greater than 9.5 values.
The final grade (NF) is obtained based on the formula:
NF = 20 * (0.30 * TP#1 + 0.30 * TP#2 + 0.30 * TEF + 0.10 * TxFreq).
