Contents

This subject represents the first contact with Electronics and Automatic Control for the students of the Degree in Engineering in Mechanical Design. It is taught in the fourth semester, after the subject "Electrical Engineering" (Third semester), whose contents are essential for the Electronics part. Its purpose is to show the student what Electronics and Automatic Control are, and present their main applications.

 

Thus, the fundamentals of electronic circuits are included in order to understand the behavior of the basic blocks of more complex systems, both in analog electronic and in digital electronic. Similarly, the basic concepts of control theory are presented, with special emphasis on the concept of feedback. The main elements of a control system are described, together with some classical techniques for their analysis, both in the time and the frequency domain. Finally, the main control actions are introduced, showing their effect on the behavior of the controlled system.

 

It is important to point out that the students are exposed to the common and independent aspect of the Electronics and of the Automatic Control. Moreover, it is important to note the practical vision of the matter. Finally, it should be highlighted that there are two main objectives for this subject. On one hand, the subject should represent a solid but easy piece of knowledge in the background of those students that will not have further contact with the fields covered. And on the other hand, the subject should be complete enough for those students that will go in deep with other subjects on the field.

 

In particular, the student must acquire expertise in the following fields:

• Current tasks in the electronic field
• Fundamental devices
• How to analyze analog electronic circuits, digital electronic circuits and power electronic circuits
• External representation of linear systems
• Time-domain analysis
• Frequency-domain analysis
• Design of simple control loops

A.- Midterm exams.

Four exams are held along the course, each one associated with one section of the contents. A prerequisite to pass the subject is a grade equal to or greater than five in all of them. The average of these four grades has a weight of 75% in the final grade.

 

B.- Laboratory sessions.

Lab sessions are graded according to the work carried out both before and during the session. The obtained score has a weight of 25% in the final grade. Attendance to all of these sessions is compulsory, and it is considered a prerequisite to pass the subject.

 

Retake exam:

There is a retake exam, in which the students have te opportunity to improve their marks in the midterm exams.

If the weighted mean is equal to or above 5 but the rest of requirements are not met, the final grade will be 4.9.
