AB This Master Thesis is framed within the research line focused on vibration mitigation in slenderstructures directed by Dr. Antol  n Lorenzana. Precisely, the work is aimed at the development, designand implementation of an active mass damper (AMD) for vibration mitigation in footbridges using astandard actuator (APS 400) commanded by a low-cost processor (NI myRIO-1900). The control law hasbeen experimentally validated on a 13.5-meter footbridge at laboratory scale and has been formulatedassuming a reduced mechanical model of the structure just considering its  rst mode.After the dynamic identi cation of the actuator, the procedure consisted in the experimental characterizationand identi cation of the modal properties of the structure (natural frequency and dampingratio) associated to its  rst mode. Once the equivalent state space system of the structure was obtained,the control law design, based on state feedback, was developed and deployed in the low-cost controller.Finally, the system was implemented on the structure and its experimental validation tests were carriedout.The system performance has been evaluated using di erent indicators both in the frequency and timedomain and under di erent loads scenarios, including pedestrian transits to demonstrate the feasibilityand robustness of the proposed system. Finally, the possibility of recalibrating the control system hasalso been included in order to optimize its performance under possible structural modi cations.
