double loop

基本解释

This paper presents a double loop controller for VVVF.
介绍一种双闭环控制变频调速系统。
Wire-o binding A method of loose-leaf binding in which a continuous double loop of wire runs through punched slots along the binding side of a booklet.
双线圈装用连续的双圈铁丝绕穿过打在书本订口的方孔而成的一种活页装。
In the double loop of control system, a PI controller is adopted in the speed loop and a vector controller is adopted in the current loop.
系统采用双闭环控制：速度环采用PI控制，电流环采用矢量控制。

Now this happens to be what we would call a linear process, because the number of times I go around the loop is directly related to the size of the argument. If I double 2 the argument, I'm going to double the number of times I go around the loop. If I increase it by five, 5 I'm going to increase by five the number of times I go around the loop.
这恰好是我们会成为,线性复杂度程序的一个例子,因为我要执行循环的次数是,和输入的参数的大小直接相关的,如果我将这个参数乘以,那么我就要将进行循环的次数也乘以2了，如果我把参数加上,那么循环的次数也要加上5了。
