Teaching in the first semester, review in January

Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The course is organized as follows: (1) Dynamics of structures in view of controlling them (2) Electromagnetic and piezoelectric transducers. (3) Integration of transducers in active structures. (4) Modeling piezoelectric structures. (5) Active damping with collocated pairs. (6) Active isolation. (7) Practical implementation (8) Introduction to advanced control techniques.

Learning outcomes of the learning unit

At the end of the course, the student will be capable of modeling electro-mechanical and piezoelectric systems, studying their dynamic behavior, and controlling their vibrations.

Prerequisite knowledge and skills

As the course is assuming some basic knowledge in automatic control, students willing to take this course should have passed one of these courses before registering to this course:
SYST0003:Linear control systems
AERO036: Spacecraft control

Planned learning activities and teaching methods

Exercise sessions, numerical simulations and laboratories.

Mode of delivery (face to face, distance learning, hybrid learning)

The course will take place each Thursday afternoon at 1.45pm, starting from Thursday the 15th of September. 
It will be organized in building B52, room +1/823.
The theoretical lecture will be organized using BBcollaborate. It will be followed by a face-to-face exercise session in the same room.
