Critical Damping in Complex Structures and Control Systems,

Abstract

This work examines the concept of critical damping normally defined for single degree of freedom systems as applied to more complex models of structures and their control systems. Here, complex models refers to lumped mass models, such as finite element models (FEM), full distributed parameter (DPS) models (described by sets of partial differential equations), hybrid systems (systems with lumped and distributed parameter elements, such as passive control systems) and active control systems consisting of the above mentioned models subject to position and velocity feedback. Recent work on critical damping of FEM and DPS models is reviewed and applied to more general linear models. (Author)
