Document Type and Number:
Japanese Patent JPH09508683
Kind Code:
A
Abstract:
A method and apparatus for structural deflection control, as well as associated sequential controls that are based on new control laws. The apparatus of this invention is of relatively low cost and performs better than prior art devices. The essence of the invention is to adjust the dynamic parameters (mass, damping, stiffness coefficients of the structure and/or input forcing coefficients) adaptive to input dynamic loads, by using the new devices and the suggested control laws. In so doing, the structure performs an adaptive function to effectively counter the effects induced by multi-directional external excitations. The required control power can be nil, or many times lower than prior art active control devices, and the effectiveness can be equivalent or even better than the current state-of-the-art active controls. The devices used by the apparatus of this invention can readily be manufactured for immediate application in structures, buildings and contents, and other constructed facilities.
