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 element of assessment.
The assessment elements will be as follows, considering each score in the [0; 1] range:
- a) T1 and T2 tests inperson;
- b) Laboratory Lab#1, with continuous oral evaluation, and final oral evaluation of PDF report;
- c) Laboratory Lab#2, with continuous oral evaluation, and final oral evaluation of PDF report;
To obtain lab frequency approval each student must obtain an average grade in the laboratories equal to or higher than 9.5 values.
To obtain approval, each student must obtain a final grade equal to or greater than 9.5 values.
Freq: Rate of attendance of practical classes.
The final grade (NF) is obtained based on the formula:
NF = 20 * (0.40 * Tests + 0.25 * Lab#1 + 0.25 * Lab#2 + 0.10 * Freq).
