  • J232013 Analysis of Postural Control on Frontal Plane of Human Body by Impulse Response Test

抄録

The mechanism of posture control in upright standing of human is not completely understood. In this study, we focus on the delay time in posture control. When a human standing system is regarding as a single pendulum system with spring, appropriate delay time depends on the natural period of the system. On the other hand, the structural natural period varies according to the stance width in standing. From the results, we assume that the delay time of posture control changes according to the stance width. Therefore, the purpose of this study is to clarify the relation between stance width and delay time of human posture control on frontal plane. We implemented impulse response test in upright standing and estimate the delay time by transfer function assuming that the system is composed of a single pendulum and control torque is generated by proportional and derivative feedback control with delayed feedback. Center of mass of human body is estimated by motion capture system in experiment. In this report, we demonstrate the delay time estimated from experimental results.
