Stability analysis and comparative experimentation for two substructuring schemes, with a pure time delay in the actuation system

摘要

In recent years there has been a focus on two types of scheme for dynamical substructure testing: the hybrid scheme (HS) and the dynamically substructured system (DSS) scheme. Although these approaches are fundamentally different in the manner of compensation/ control, the comparative performance of the schemes has not yet been studied in simulated or real experimental tests. This paper studies the performance of these schemes via tests on a simple base-isolated structure with a natural rubber bearing.
