Adaptive vibration control of a bridge and heavy truck

Bridge vibration control is an important issue whose purpose is to extend the structural service life of steel bridges. Normally, the bridge is modeled as an elastic beam or plate subject to a moving vehicle. However, the moving truck on a bridge is a complicated problem that must still be researched. In this paper, we propose a solution using a time varying model coupled-with a black box identification method. This solution does not require an exact physical model. It uses a hybrid multi-channel adaptive vibration control technique that combines feed forward and feedback active control. Our system is called the Intelligent Vehicle/Bridge System (IVBS).
