Abstract: New digital control algorithms have been developed to achieve the desired transmissibility function for a microgravity isolation system. Two approaches have been presented for the controller design ...

Abstract: Preliminary design of a structure controlled by active bracing or mass dampers to withstand seismic motion or high winds requires rapid means of analysis and estimates. A response spectrum technique applied to simplified ...

Abstract: An active bracing system has been designed and fabricated for implementation to a full‐scale dedicated test structure for structural response control under seismic loads. Presented in this paper, the first part of a two‐part ...
