When human gravity center was out of equilibrium owing to disturbance, there would be a dynamic process to equilibrium state. This process comes with neural system and motion system. In order to simulate this process well and truly, this paper provides a candidate method based on SimMechanics, where under the premise of local linearization of motion system and PID controller abstracted for neural system, human body dynamics including body, motion system and central nervous system is modeled. On the other hand, the model parameters were adjustable according to the actual gender, weight and height. Through the comparison with the real gravity data, it was demonstrated that the presented simulating method is feasibility and rationality. At the same time, through the simulation, we could provide practical data support to research on algorithm development for the evaluation of human balance capability.

This paper studies the stabilization to an inverted pendulum under a delayed proportional-derivative-acceleration(PDA)feedback,which can be used to understand human balance in quiet *** closed-loop system is described by a neutral delay differential equation(NDDE).The optimal feedback gains(OFGs)that make the exponential decaying rate maximized are determined when the characteristic equation of the closed-loop has a repeated real root with multiplicity *** a property is called multiplicity-induced dominancy of time-delay systems,and has been discussed intensively by many authors for retarded delay differential equations(RDDEs).This paper shows that multiplicity-induced dominancy can be achieved in *** addition,the OFGs are delay-dependent,and decrease sharply to small numbers correspondingly as the delay increases from zero and varies slowly with respect to moderate ***,the inverted pendulum can be well-stabilized with moderate delays and relatively small feedback *** result might be understandable that the elderly with obvious response delays can be well-stabilized with a delayed PDA feedback controller.
