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 本文較系統(tǒng)地綜述了由peterj . olver和m . fels推廣的活動標架理論。
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 論文從控制系統(tǒng)的結(jié)構(gòu)方面,利用結(jié)構(gòu)不變性原理,針對位置擾動設(shè)計專門的前饋補償控制器,減小位置擾動的影響。
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 論文闡述了多余力產(chǎn)生的機理,研究了影響多余力的因素,在控制策略方面,采用了結(jié)構(gòu)不變性原理,建立加載系統(tǒng)等效的結(jié)構(gòu)不變性系統(tǒng),從根本上來減小多余力的影響。
百科解釋
Invariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties from the point of view of their effect on functions. Classically, the theory dealt with the question of explicit description of polynomial functions that do not change, or are invariant, under the transformations from a given linear group.
