Control of vibrational systems [PDF]

open access: yesIEEE Transactions on Automatic Control, 1994
Summary: Vibrational systems, characterized by their second-order or ``spring-mass'' nature, occur throughout engineering. Examples range from lightly damped structures, such as the proposed space station, to regional power system models. While the study of such vibrational systems has a long and rich history, concern has traditionally focused on the ...

Proposal of deformation history integral‐type hysteresis model considering performance change of high‐damping rubber bearings and verification using substructure real‐time online testing system for seismically isolated structure

open access: yesJapan Architectural Review, 2023
A deformation history integral (DHI)‐type hysteresis model is an elastic–plastic model that was originally developed for high‐damping rubber bearings (HDRs). The model can show the complex characteristics of HDRs.
