人体运动系统建模和分析的核心问题包括(1)肌肉肌腱动力学,(2)生物力学系统的动力学和运动学,以及(3)神经控制和系统作为开环或闭环过程的制定之间的关系。本文将在两个特定的运动系统的背景下解决这些问题。首先要解决的是人类的视觉系统。眼动系统是研究人类运动控制的理想系统,因为它们具有相对低的维度,并且比其他神经肌肉系统更容易控制。通过仔细观察眼球运动的轨迹,可以推断出运动神经元活动的影响,推断出中枢神经系统的控制策略,并系统地观察控制中扰动的影响。本文还将介绍该运动控制系统的一个应用。特别是,人类步态模型的目的是开发相关的神经控制骨骼成员的应力状态。这是通过将人体建模为由最小肌肉集控制的铰接刚体段的集合来实现的。神经信号作为输入到肌肉肌腱动力学和由此产生的肌肉力量,关节力矩和所产生的运动的节段模型的推导。
Issues that are central to the modeling and analysis of a human movement system include (1) musculotendon dynamics, (2) the kinetics and kinematics of the biomechanical system, and (3) the relationship between neurological control and the formulation of the system as an open or closed loop process. This paper will address these problems in the context of two particular movement systems. The first to be addressed is the human ocular system. Eye movement systems are ideal for studying human control of movement since they are of relatively low dimension and easier to control than other neuromuscular systems. By scrutinizing the trajectories of eye movements it is possible to infer the effects of motoneuronal activity, deduce the central nervous system’s control strategy, and systematically observe the effects of perturbations in the controls. An application of the locomotory-control system will also be presented in this paper. In particular, a model of human gait is developed for the purpose of relating neural controls to the state of stress in a skeletal member. This is achieved by modeling the human body as an ensemble of articulating rigid-body segments controlled by a minimal muscle set. Neurological signals act as the input into the musculotendon dynamics and from the resulting muscular forces, the joint moments and resulting motion of the segmental model are derived.
