Active Self-tuned Mass Damper for Vibration Control and Continuous Monitoring of Civil Structures

摘要

Several examples of control strategies for the seismic protection of civil structures, ranging from passive to active andsemi-active have been presented in the scientific literature, and often applied in the market. However, none of themproved to be absent of high employment costs or burdensome installations. For this reason, the low-cost Active MassDamper (AMD) shown in this work and capable of automated self-tuning, control and continuous monitoring of thestructures represents an attractive solution. The device has been designed and tested on the numerical model of a scaledsteel made three story building. In particular its working principle and the ISAAC algorithm for automatic identificationare presented and its robustness against modelling and estimation errors is analyzed. The methodology allows to avoidthe study of specific solutions for each case, thus making possible the adoption of such systems also for already existingand common structures.
