Modeling and Control of Aerospace Vehicles
Objectives
In this curricular unit the students will have a broad perspective of the various types of aerospace vehicles and the main modeling, analysis, and control methods used for these vehicles, understanding their potential but also their limitations. Simultaneously, the students will develop know-how and experience of designing and implementing concrete control strategies for this type of vehicle.
To this end, the intended learning outcomes for this curricular unit are the following:
OA1. Revise classical control systems analysis and design tools;
OA2. Formulate control system models for simple aerial and space vechicle;
OA3. Analyze and design control systems using a state-space techniques;
OA4. Analyze and design control systems using a MIMO frequency domain techniques;
OA5. Develop solutions to concrete control systems problems in aerospace.

Prerequisites
Students should have a strong foundation in Linear Algebra and Mathematical Analysis, which are typical for most engineering students. Taking introductory courses in signals, systems, and in control systems is recommended, and an additional self-study effort might be necessary, for which specific bibliography will be suggested.

Teaching method
The course is organized in theoretical-practical classes and practical classes. In the theoretical-practical classes the concepts are introduced and applied in concrete cases from an analytical point of view. In addition, the practical (or laboratory) classes are directed to work on further analytical problems tipical of the TP class topics under study, as well as to the development and implementation of techniques applied to concrete cases, with the goal to obtain experimental results and their analysis.
The course may use a Blended Learning (B-Learning) methodology, where new contents are breafly introduced asynchronously using Moodle, while the synchronous classes are used to consolidate the contents, addressing students'' questions, and solving more complex problems. The use of active learning techniques will also be encouraged.
Evaluation method
The final grade (F) is defined as: F = 0.5*T + 0.1*Q + 0.4*L
- Tests (T): the theoretical-practical component will be primarily evaluated through 2 tests.
- Online quizzes (Q): Moodle short-quizzes and other online assessment tools.
- Laboratories (L): lab assignments to promote a deeper understanding, applied to concrete scenarios.
The assessment components Tests (T) and Online Quizzes (Q) are considered the theoretical-practical component, for which there is the final exam as an alternative. The lab assignments (L) will count as the laboratorial assessment grade.
Both T and L components have a minimum grade of 9.5 points in 20.
