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.

9625715 Patten PI 提出了一项为期三年的研究计划，该计划将确定用于桥梁冲击振动控制的半主动减振器 (SAVA) 的有效性和可实施性。该提案的目的是对 SAVA 应用到 ODOT（俄克拉荷马州交通部）测试桥所引发的工程问题进行长期研究。 该研究将检查不同控制算法的测试，包括反馈线性化和基于李亚普努方法扩展的非线性双态控制。 将开展工作来验证开发和测试的性能。 该研究还将解决执行器的最佳拓扑问题，包括：（a）执行器的运动学布置； (b) 执行器的最佳位置和放置； (3)执行器数量的影响。
