A new evaluation method for human dynamics has been proposed based on the measurement of swaying condition in the standing position. This measures the center of gravity of a subject when a simple load is applied to him. The aim of this measurement is to evaluate the ability of stance posture control of a subject. The control system was identified by using an auto-regressive moving average exogenous model and an extended least squares method, and then its transfer function was obtained in a discrete form. The effectiveness of the system identification was confirmed by the experimentand simulation. In order to characterize its control performance, the poles of the transfer function were all plotted in a z-plane. This mapping approach well indicates the human stance condition.
