摘要：An absolute displacement sensor includes a sensor housing serving as adetection object; a mass body having a mass m which is movably supported by the sensor
housing with a spring coefficient k and a damping coefficient c; a detecting means whichelectrically detects a relative velocity of the sensor housing with respect to the massbody a feedback control means which controls the absolute displacement of the massbody attributable to the absolute displacement of the sensor housing by positivelyfeeding back the relative displacement and by negatively feeding back a relative
acceleration obtained by primarily differentiating the relative velocity, respectively; and aphase lag compensation means which performs phase lag compensation with respect tothe relative displacement.
