项目摘要

The ground vibration caused by the urban elevated highway bridge vibration under traffic flows affect the bridge's seviceability and nearby buildings. The purpose of this project is to realize the active vibration control of the highway bridge vibration. So, we make an actuator for the vibration control experimentally and design a controller using by DSP (digital signal processor). In this project, we have studied as follows, (1) the optimal control method of bridge vibration, (2) trial manufacture of actuator and design of controller, (3) the CAD system for vibration control and system identification, (4) field tests for bridge vibration control.Results obtained in this project are summarized as follows :(1) The expanded instantaneous control law is derived. Applying the new control law, the LQG control to the bridge traffic vibration can be formulated with the Kalman filter.(2) In order to construct the control system for the bridge vibration, we made a trial manufacture of actuator and design a controller using by DSP.(3) The vibration CAD system by the MATLAB languate for moldering and the measurement CAD system by the Lab VEW software for structural identification are realized.(4) On filed tests of pedestrian bridge, we confirm effectiveness of active vibration control by the proposed system.

城市高架公路桥梁在车流作用下振动引起的地面振动影响桥梁及附近建筑物的使用性能。本项目的目的是实现公路桥梁振动的主动振动控制。因此，我们实验制作了一个用于振动控制的执行器，并设计了一个使用DSP（数字信号处理器）的控制器。在本项目中，我们进行了以下研究：（1）桥梁振动优化控制方法；（2）作动器试制及控制器设计；（3）振动控制CAD系统及系统辨识；（4）桥梁振动控制现场试验。本项目取得的成果总结如下：（1）推导了扩展瞬时控制律。应用新的控制律，可利用卡尔曼滤波器制定对桥梁交通振动的LQG控制。(2)为了构建桥梁振动控制系统，试制了执行器，并设计了采用DSP的控制器。(3)实现了利用MATLAB语言进行成型的振动CAD系统和利用Lab VEW软件进行结构识别的测量CAD系统。(4)现场试验对于人行天桥，我们确认了所提出的系统主动振动控制的有效性。
