Optimal tuned outrigger-ATMD systems considering seismic and wind loads
https://orcid.org/0000-0002-4017-4617
Abstract This paper formulates the optimal feedback control model for the outrigger-active tuned mass damper (ATMD) system and investigates the influence of some input variables on the control effect while considering seismic and wind loads. The paper first deduces the joint equation of motion of the outrigger-ATMD system. Different control theories are then used to formulate the optimal control force, the optimal frequency tuning, and the optimal damping tuning. Based on such optimal tuned outrigger-ATMD systems, sensitivity analyses for variables from the ATMD and outrigger system are implemented. With many carefully selected schemes, the control effect and efficiency of the control model of the ATMD are verified in the frequency domain and time domain. It is observed that the fixed-points theory is a better choice for the ATMD tuning and the supplement damping in the outrigger system will suppress the control performance of the ATMD.
Highlights Optimal control model for the outrigger- ATMD system. Pseudo excitation method-based simplified models of outrigger- ATMD system. Sensitivity analyses for variables from the ATMD and outrigger system. Fixed-points theory-based optimal tunned outrigger- ATMD system.
