Specialization in Defence: This subject contributes to the training of the Army Officers, developing the technical knowledge in automatisms and control methods that the Army Officers need to perform their duties.
1.3. Recommendations to take this course
Although not a mandatory requirement, for pedagogical reasons it is advisable to have successfully passed the subjects of Mathematics (30100, 30106, 30111) and Physics (30101, 30107). Having studied these subjects, the student will possess the necessary basic knowledge and tools to follow the course without difficulty.
Diligence, by means of continuous study, is fundamental to successfully pass the course. Students are encouraged to resolve any doubts that arise as soon as possible. Since the course builds incrementally on the explained topics, the lack of comprehension of some subject may hinder the student's ability to assimilate later ideas.
2.1. Competences
On passing the subject, the student will have acquired the following competences:
-
C04 - Ability to solve problems and take decisions with initiative, creativity and critical reasoning.
-
C07 – Ability to use techniques, skills and tools necessary to practise engineering.
-
C33 - Knowledge about the fundamentals of automatic responses and methods of control.
2.2. Learning goals
In order to pass this subject, students must demonstrate the following results:
- Identifies the relevant subsystems and their interconnections to automate the overall system operation.
- Selects the most appropriate modelling, analysis and design techniques according to the control requirements.
- Applies the techniques and methods for the design of the control system complying with the performance specifications.
2.3. Importance of learning goals
The knowledge acquired by students in Automatic Systems initiates them in the control and automation of a large number of industrial activities. A large part of these tasks or processes fall into two main groups:
- Knowledge about continuous systems allows them to tackle tasks such as motor speed control, position of mechanisms, temperature control, torque control, flow control...
- The knowledge about discrete event systems allows them to tackle tasks such as the control of manufacturing operations, assembly lines, maintenance, storage...
Nowadays, a high degree of automation has been reached in these processes. This is achieved by means of regulators, industrial computers, programmable logical controllers, robots...
The learning results of this course provide students with the ability to analyze and control real systems comprising actuators and industrial processes, and enable them to propose control schemes and calculate the appropriate control parameters to meet given operating requirements. These results, and the capacities and skills derived from them, are of great importance in technological and industrial environments, where the control of processes and systems is a key and fundamental piece for the development of the product, enabling costs reductions, both economic and environmental, and increasing the final quality of the product.

SPECIALIZATION IN BUSINESS
The learning process designed for this subject is based on the following:
- Lectures: Theoretical activities imparted in a fundamentally expository way by the teacher, in such a way as to expose the theoretical supports of the subject, highlighting the fundamental content, structuring it in themes and relating those themes to each other.
- Practice Sessions: The teacher explains and helps in understanding the use and management of necessary software for configuring and programming control devices (PLC’s)
- Laboratory practices: Students will perform tests, measurements, assemblies, etc. in the laboratories arranged in groups, following a script provided by the teacher.
- Individual tutorials: They will be carried out in the department through personalized attention to the student, with the goal of solving the doubts and difficulties the student faces. These tutorials can be carried out either face-to-face or virtually.
The approach, methodology and assessment of this guide are intended to be the same for any teaching scenarios. They will be adapted to the social-health situation at any particular time, as well as tothe instructions given by the authorities concerned.
