Resum
This paper lies in the framework of a parametric numerical analysis of the efficiency of active mass dampers (AMDS), focusing on the influence of time delays. Such a lag time is contributed by all the elements in the control loop but is mostly due to the physical inertia of the actuators; consequently, since mass dampers are massive, time delays can be significant for AMDS. The time evolution of the system is simulated by means of a difference equation describing the digital control loop. Active...
