Fractal theory takes non - linear complex systems as its objects and is an effective method to solve complex problems 分形理論是以復雜的非線性系統(tǒng)為研究對象的,是解決復雜性問題的有效方法。
Linear - complex singularity of stewart manipulator is defined on the basis of the conception of linear complex . according to the pitch of instantaneous screw motion in singular configuration , all singularities of stewart mechanism are classified into three different kinds 引入線幾何中線性叢的概念,定義了stewart機構(gòu)的線性叢奇異,并以奇異時瞬時螺旋運動的節(jié)距將奇異分為三類。
