Objectives
1. To learn the basic technologies and methodologies of the industrial automation.
2. To develop the abstract reasoning capabilities on identifying possible models and solutions for small to medium complexity automation problems, with the help of the learned methodologies and technologies.
3. To give the students the capability of implementing true automation solutions, namely by laboratory practice.
4. To inhabit the students on searching for adequate automation equipments, available on the market, for different automation problems.
Subject matter
1. Introduction to automatic systems: automation, control and supervision.
2. Automatic systems specification.
3. Automation with electromagnetic technology.
4. Common electromagnetic control schemes.

Evaluation method
Approval in the course unit ''Automação'' can be achieved through one of two alternative forms: (1) continuous evaluation or (2) final exame after laboratorial evaluation.
A frequency grade is not required to be admitted to the final exam. Class attendance is free and will not be evaluated.
1. Continuous evaluation
This grade modality includes 2 mini-tests (theoretical-practical part) and 2 laboratorial works. The mini-tests are weighted at 50%, and the lab works are weighted at 50% for the final average course unit grade. The approval grade must be at least 9.5 values, in a 0-20 scale.
The lab works are to be done in group with a maximum of 3 people. The lab grade will be based on work reports and work demonstrations on programmable logic controllers for all the alumni in the group. In general, the lab grade will be equal for all the elements of the group. However, if strong discrepancies are detected in the work evaluation and performance among the group elements, the group grade may be downgraded by 1 to 3 values.
2. Final exame after laboratorial evaluation
The grade obtained in the final exam will be weight 50% for the final grade. The remaining 50% weight will come from the lab grade. Both these grades will be averaged, with decimal approximation, to get the final course unit grade. The approval grade must be at least 9.5 values, in a 0-20 scale.
This methodology will be used both for alumni who want to improve their approval grade, as well as for alumni that have not yet been approved through the continous evaluation.
3. Alumni which have already attended the course unit in previous years
The students who have already attended the course unit in the years 2012/13 or 2013/14 can use the frequency grades obtained in those years as grades for the laboratorial part of the course unit evaluation.
