Control of aerospace systems
Bachelor in Aerospace Engineering (Plan: 421 - Estudio: 251)


Department assigned to the subject: Systems Engineering and Automation Department

Type: Electives
ECTS Credits: 6.0 ECTS


Requirements (Subjects that are assumed to be known)
Calculus I Calculus II Linear Algebra Programming
With this subject the students are aimed to acquire basic knowledge on analysis and control of dynamic systems in continuous time, with application to aerospace systems. The study of the behavior of the systems will be carried out by means of the classic control theory.
