In order to keep in control the long and large bridges whose vibration by external loads is fatal to their own structure, the adoption of wired system for vibration control entails some problems such as high initial set-up cost and onerous maintenance. This paper attempts to solve the problems by developing a TCP/IP based wireless vibration-control system which fits better outdoors and also by applying Lyapunov algorithm which has been proven to work well for semi-active control system. The performance of the Lyapunov -algorithm-applied wireless vibration-control system was evaluated through experiments with a model structure and a semi-active control device both of which were designed for this particular research. The experiments proved the wireless vibration-control system developed here was effective.
