Semi-active base isolation for a building structure

International Journal of Computer Applications in Technology, 1999
Abstract Semi-active control methods, where coefficient of viscous damping or spring constant are changed effectively according to the state of control object, have received much attention from control performance and energy consumption. This study deals with the application of semi-active control method to base isolation control.

Semi-active reflector antennas

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
Semiactive multimatrix reflector antennas offer efficient reconfigurability for multibeam payloads and have growth potential. The basic idea is to introduce multiport hybrids or matrices between the amplifiers and the feed elements. These include four-port hybrid couplers and phase shifters, like Butler matrices.

A Semi-active Control System for Wind Turbines

2014
A semi-active (SA) control system based on the use of smart magnetorheological (MR) dampers to control the structural response of a wind turbine is proposed herein. The innovative approach is based on the implementation and use of a variable-properties base restraint.

Optimal semi-active vibration absorber for harmonic excitation based on controlled semi-active damper

Smart Materials and Structures, 2014
The semi-active vibration absorber (SVA) based on controlled semi-active damper is formulated to realize the behaviour of the passive undamped vibration absorber tuned to the actual harmonic disturbing frequency. It is shown that the controlled stiffness force, which is emulated by the semi-active damper to realize the precise real-time frequency ...

"Mitigation of seismic vibration by semi-active control"

2010
Theoretical and practical issues concerning the multi-faceted task of mitigating the latero-torsional seismic response of a prototypal frame structure with asymmetric mass distribution are approached. Chevron braces with embedded magnetorheological dampers acting on the interstory drift are used to provide energy dissipation.
