• We have developed an original jerk sensor that uses the derivative of acceleration(also called jerk)as its control input. And we evaluated the characteristics of a vibration-control system which applies this jerk sensor 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 we clarified that the jerk sensor operated correctly. That is, the gain increased by 20dB per decade and the phase of jerk lead that of acceleration by 90 degrees(as it theoretically must). And the analytical calculations for step response agreed well with the experimental results. Moreover, the possibility of improving the speed of response by using direct jerk-feedback control was confirmed.
