Abstract: The efficient evaluation of human equilibrium function is important for people with organs degradation and dysfunction. The traditional evaluation of static and dynamic equilibrium function seems efficient, but the prepared participants restricted the experimental results to be objective and genuine. For evaluating the equilibrium function efficiently, we propose a wavelet-based dynamic model of the human body using external excitation. Firstly, we introduce a local linearization method based on the second-order Taylor expansion for simplifying typical linear system model. Secondly, the continuous wavelet transform analysis is applied to process gravity-center data and estimate parameters of the dynamic model. Finally, the settled time of the systemic responding rapidity is evaluated. Furthermore, the index of the equilibrium ability is obtained. Experiment results show the validity and practicability of the proposed method.


Keywords: Leave dynamic model, Equilibrium ability, Wavelet analysis, Settling time, Passive motion.
