Full Scale Semiactive Bridge Control

Patten PIs提出了一项为期三年的研究计划，以确定半主动振动吸收（SAVA）在桥梁冲击振动控制中的有效性和可实施性。本提案的目的是对在ODOT（俄克拉何马州交通部）测试桥上应用SAVA所引起的工程问题进行长期研究。该研究将检验不同控制算法的测试，包括反馈线性化，以及基于Lyapunou方法扩展的非线性双状态控制。将进行工作以验证所开发和测试的性能。该研究还将解决致动器的最佳拓扑问题，包括：(a)致动器的运动学安排；(b)执行器的最佳位置和放置；(3)执行器数量的影响。

9625715 Patten PIs proposed a three year program of research that will establish the effectiveness and implementability of semiactive vibration absorbs (SAVA) for bridge impact vibration control. The purpose of this proposal is to conduct a long term study of the engineering issues raised by the application of SAVA to the ODOT (Oklahoma Dept. of Transportation) test bridge. The research will examine the testing of different control algorithms including feedback linearization, and a nonlinear bi-state control that is based on an extension of Lyapunou's method. Work will be conducted to verify the performance developed and tested. The research will also address the question of best topologies for actuators, including: (a) kinematic arrangement of actuators; (b) optimal location and placement of actuators; and (3) effect of number of actuators.
