Active control of structural vibration by an active mass damper. Comparison between the performance of active mass damper and passive mass damper against the earthquake motion.

Abstract

The application of active control theory to suppress the vibrations of large scale electric structures has gained much interest. an important aspect of active control system design is the amount of control power which must be supplied to the actuators especially in large structures. The objectives of this paper are: (1) To investigate the effectiveness of using active mass damper system for reducing the acceleration response of structure under earthquake ground motion, and (2) To compare the performance characteristics of active mass damper and passive mass damper systems evaluating the control force and control power through computer simulations.
