Fractal theory takes non - linear complex systems as its objects and is an effective method to solve complex problems 分形理论是以复杂的非线性系统为研究对象的,是解决复杂性问题的有效方法。
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 引入线几何中线性丛的概念,定义了stewart机构的线性丛奇异,并以奇异时瞬时螺旋运动的节距将奇异分为三类。
