摘要
目的是建立人工心脏控制系统的运动模型.心脏的搏动是有规律的,但在外界干扰下,可能会突然改变运动规律,经过短暂的过渡时间,进入到新的运动状态.心脏的运动具有突变特性.突变理论主要的研究对象是非线性运动,使用的数学工具是势函数,通过使用势函数对心脏的非线性运动进行研究,为建立人工心脏控制系统建立起了势函数数学模型.使用人工心脏势函数运动模型可以对心脏的运动规律进行定量分析,进而对心脏运动进行更深入的研究.
The purpose of the article is to build a beating model for artificial heart.The beating of a heart is regular, but it may be irregular for the disturbance from outside environments, and it enters a new state after a short while. The moving of the heart is of catastrophe characteristic. The theory of catastrophe, which uses the potential energy function as its mathematics tools to discuss mainly the problem of nonlinear moving. By research on the nonlinear moving with potential energy function, the mathematics model is built for the moving of artificial heart. The model of artificial heart can be used to analyse the moving of heart by details , further more we can do deeper research on human heart moving.
