Modeling of human balance as an inverted pendulum

Abstract

From a biomechanical point of view, maintaining the balance is the human ability which is gained with the evolution of its body. In order to maintain a vertical posture nervous system all the time stimulates the musculoskeletal system to continuous motion. This movement is in a rocked slightly sagittal planes and frontal, reminds their behavior inverted pendulum. It should be noted that in the case of the classic inverted pendulum its upright position is held by changing position of the cart relative to the ground. In contrast, man is not moving relative to the ground maintains its position through changes in muscle tension.. Projection of the center of gravity is located on the ground in the contour of the human feet. It means that for some sets of assumptions human body can be modelled as inverted pendulum with the various kinds of its complexity. Article presents authors approach to modelling and simulation of human balance system.
