Research Abstract

In nearby urban elevated highway bridges, the ground vibrations caused by the traffic induced vibrations affect the buildings. This project studies the active vibration control to the traffic induced vibrations by the several control laws. In order to the realize active vibration control for the elevated bridges, we need to solve the problems as follows.
(1) to predict the state variables of the moving vehicles from the informations obtained by the observation points of the bridge.
(2) to obtain the optimal control laws for the time variant systems.
(3) to develop the actuator to generate the desirable control forces.
Results obtained in this project are summarized as follows :
(1) Applying the Kalman filter to the bridge-vehicle-road system, we can predict the state variables of the bridge-vehicle system from the informations of one observation point on the bridge. By combing the optimal feedback control and the Kalman filter, the stochastic control law can be formulated.
(2) A new control law for the time variant system can be obtained by expanding the instantaneous optimal control theory. The effectiveness of the control law is confirmed by the numerical simulations.
(3) The trial construction of actuator was done. We did the vibration control tests of the pedestrian bridge using by the actuator. On the results of the test, the effectiveness of the actuator is ascertained.
