Objectives

The aim of this course is to provide the future graduates with a set of basic and structuring concepts on Industrial Automation.  The unit will  present and develop a set of concepts and knowledge in the field of sensors and actuators (pneumatic, hydraulic, and electrical) as well as the components for their implementation. It is thus intended that students acquire the ability to dialogue with experts and are able to make choices, technically and scientifically based, among various solutions that a particular problem may require.

Learning outcomes and competences

By the end of this course, the student will be able to:

• Identify sensors, control equipment, and actuators used in automation systems;
• Specify and select the different automation components;
• Describe the mode of operation and applicability of the various equipment used in automation systems;
• Design solutions using pneumatic, hydraulic and electromechanical drive technologies;
• Interpret pneumatic and hydraulic circuits.

 

Working method

Teaching methods and learning activities

The course has theoretical classes in auditorium and theoretical-practical classes in the laboratory. The lectures are exposure of program materials, supported by audio-visual means and must be seized by students through additional study activities and conceptualization. The practical lessons taught in different laboratories to give an overview about sensors and actuators used in industry.
In the Instrumentation laboratory, students will have the opportunity to assemble and test different types of sensors, as well as to read them through data acquisition systems; in the laboratories of pneumatic and hydraulic will proceed to the assembly, and test of circuits using the two technologies, as well as electro-pneumatic systems. Finally, in the automatic control lab the students will have the opportunity to  see how the information flows from the sensor to the control element and then to the actuator in an automatic way, thus closing the learning cycle.
In addition to these activities, and outside the class, students will carry out research work on the latest technologies (virtual reality, augmented reality, IoT, etc.) that will present in the TP class.
Finally there will be a visit to a company that uses automatic systems, makes great use of automatic systems.

Eligibility for exams

To be admitted to exams, students have to be enrolled in the course and
not exceed the absence limit allowed in the General Evaluation Rules of FEUP.
It will also be considered the frequency of the students who have attended the UC of Industrial Automation.

Calculation formula of final grade

The final classification of ordinary students is based on a written evaluation test (PE) and a report (REL). These components are rated from 0 to 20 and have the following weights:
PE - Individual written test, to be carried out at the time of examinations, 70% of the final classification;
REL - Written report on the latest technologies in industrial automation carried out in a group (maximum of 4 students), to be delivered in the middle of the semester. This report will be presented orally during a theoretical-practical class (20% of the final classification).
TL - Participation in laboratory work, carried out in a group in the classroom - 10% of the final classification.

IMPORTANT NOTES:
- Failure to complete the report corresponds to a mark of 0.
- Not attending TP classes will result in a penalty in the TL component.
- Access to the PE exam, as well as the preparation of the report, requires the frequency of the course unit (except for students who, according to the FEUP rules, enjoy special status that exempts them from class attendance).
- Students who have been attending but have not obtained approval after the normal period can repeat the written test at the later time, keeping the remaining classifications of report and laboratory evaluation.

The final classification = 0.70*PE + 0.20*REL + 0.10*TL

Examinations or Special Assignments

Not applicable.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

The students with special status may choose to attend the course as ordinary students, submitting themselves to a similar evaluation.
In alternative, the student must be submitted to one written exam that represents 75% of the final classification and a oral exam that represents the other 25 % of the final classification.
However, to get access to the oral exam, the student must have a result equal or superior to 7 marks (in 20) on the written exam.

Classification improvement

Students who wish to obtain an improvement in his/her classification may repeat the written test (PE). The final grade is obtained according to the referred to in the "Calculation of the Final Evaluation", being for this purpose the remaining classifications obtained previously.
