The paper presents the design, ongoing construction and digital implementation of an experimental set-up consisting of a scaled-down five-storey frame structure equipped with an active mass damper on the top floor and excited by a shaking table. The experimental set-up will serve for testing innovative control algorithms that adaptively account for system constraints, such as force saturation and limited stroke extension of the inertial actuator, in a general framework of robust non-linear control. The results of preliminary experimental tests are presented in the paper in order to show, to some extent, the ability of the system to work in real-time closed-loop conditions with a “skyhook” control algorithm.

Abstract
The paper presents the design, ongoing construction and digital implementation of an experimental set-up consisting of a scaled-down five-storey frame structure equipped with an active mass damper on the top floor and excited by a shaking table. The experimental set-up will serve for testing innovative control algorithms that adaptively account for system constraints, such as force saturation and limited stroke extension of the inertial actuator, in a general framework of robust non-linear control. The results of preliminary experimental tests are presented in the paper in order to show, to some extent, the ability of the system to work in real-time closed-loop conditions with a “skyhook” control algorithm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
