The demand for the reduction of vibration of huge structure like ships or buildings has become more important subject. Under the circumstances, in order to ensure less vibration and more comfortable living or working environments, a number of vibration reduction devices have developed. Among them, the dynamic damper is known very well. There is two typical type of the dynamic damper. One of them is called "TMD" (Tuned Mass Damper), the other is called "TLD" (Tuned Liquid Damper). In these days as the rapidly advanced of computer technology, active control technique has been practical use. The authors developed a new type of TLD, which has adjustment mechanism of tuning of the natural frequency. In order to realize higher performance of reduction of vibration, This paper presents a study on the development of TLD controlled by active (hybrid) control technique. The simulation calculation and model test were carried out. From the simulation calculation and model test, it became obvious that this new type TLD has a higher performance than the TLD with passive control system. And from the model test, it confirmed that that TLD with hybrid control system would be available practical use.
