The Study on High Building Structures Decentralized Vibration Control

Article Preview

Abstract:

An interesting result that has been observed here is that systems that have two-level hierarchical control can exhibit a special form of fault-tolerance.. This concept is illustrated using an example of displacement control in a 4 floor building subject to seismic excitation. The two-level system performance, for both actuator malfunctions and model uncertainties is compared with a centralized robust control design using H-∞ optimization with respect to the exogenous seismic inputs.
