Control Technology
Objectives
1. Learning the methodologies and technologies of industrial automation and industrial control.
2. Provide students with abstract reasoning skills in modeling automation processes from low to medium complexity.
3. Develop in students the ability to realize practical solutions for automation and control, namely with the use of laboratory practice.
4. Develop in students the ability to search for solutions and equipment suitable for different automation and control problems, available on the market.

Teaching method
Theoretical-practical classes: presentation of theoretical concepts, analysis of 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 written in Moodle;
- 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;
- d) Laboratory Lab#3, with continuous oral evaluation, and final oral evaluation of PDF report.
To obtain frequency each student must obtain a grade equal to or higher than 7.0 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 * (0.25 * Tests + 0.20 * Lab#1 + 0.20 * Lab#2 + 0.20 * Lab#3 + 0.15 * Freq).
