This paper presents results obtained from analytical and experimental studies to evaluate the characteristics of a vibration-control system that employs a sensor for changes in acceleration (also called jerk). We have developed an original jerk sensor that uses the derivative of acceleration as its control input. We evaluated the characteristics of a vibration-cotrol system which applied this jerk sonsor for direct jerk-feedback control. As a control model, we used a one-degree-of-freedom servo system. Analytical and experimental approaches were compared, and the following became clear: (1) The jerk sensor operated correctly. The gain increased 20 dB per decade and the phase of jerk lead that of acceleration by 90 degrees, as it theoretically must. (2) The analytical calculations for step response agreed well with the experimental results. (3) The possibility concerning the improvement of the speed of response was confirmed.
