摘 要：
方框图表征了自动控制系统的结构和原理,对方框图进行等效变换可以得到系统的传递函数,进而对自动控制系统进行分析.通过对系统方框图的元素构成和不同等效方法进行研究发现,相加点和分支点的移动是方框图等效变换求系统传递函数过程中的关键步骤.对构成系统方框图的元素和几种联接方式进行系统详细的介绍,并通过对相加点和分支点的前移以及后移进行分析比较,总结提出快速准确解决此类问题的方法.

摘 要：
Block diagram is used to characterizes the structure and principles of automatic control system.The equivalent transformation of block diagram causes the systematic transfer function,which gives insight into the automatic control system analysis.The study of elements formation and different equivalent methods shows that adding points and branch points move is the key step in equivalent transformation from block diagram to systematic transfer function.A detailed survey of constituent elements and connective ways are made.A comparison of summing-point and branch-point forward and backward move proposes the efficient and accurate solution to relevant problems.
