footbridges are susceptible to excessive level of vibrations caused by human loading. Active
vibration control (AVC) via inertial mass actuators has been shown to be a viable technique
to mitigate vibrations, allowing structures to satisfy vibration serviceability limits. Most of the
AVC applications involve the use of SISO (single-input single-output) strategies based on
collocated control. However, in the case of floor structures, in which most of the vibration …
