This paper proposes a new type of absolute displacement and velocity sensor based on the principle of servomechanism. Because measuring range of the absolute displacement is over natural frequency, it is difficult to measure a low frequency vibration using conventional seismic type sensor. In order to expand measuring frequency range toward low frequency, the sensor with the low natural frequency is realized by using feedback control techniques. It is demonstrated that the developed sensor with feedback and phase lag compensations have 0.6Hz of natural frequency to measure from 1Hz to 100Hz and it is available to reduce the natural frequency for attempting more low frequency measuring range. This sensor is used for controlling structural vibration using active dynamic vibration absorber.
