不变量理论

This paper surveys the algorithmic theory of moving frames developed by peter j . olver and m . fels . their applications to geometry , classical invariant theory are indicated
本文较系统地综述了由peterj . olver和m . fels推广的活动标架理论。
By applying the structure invariant theory in the control strategy , the feedforward - feedback control theory is applied in the control system design to reduce the redundant force
论文从控制系统的结构方面，利用结构不变性原理，针对位置扰动设计专门的前馈补偿控制器，减小位置扰动的影响。
So how to minish the surplus torque by selecting proper control strategy is a main aspect discussed in this paper . by applying the structure invariant theory in the control strategy , an equivalent structure invariant loading system is produced , which proved to be very effective in reducing the redundant force
论文阐述了多余力产生的机理，研究了影响多余力的因素，在控制策略方面，采用了结构不变性原理，建立加载系统等效的结构不变性系统，从根本上来减小多余力的影响。
