imaginary axis

基本解釋

The selection of weighting function matrixes and the controller design method for a plant with a pole on imaginary axis is discussed in detail.
詳細(xì)討論加權(quán)函數(shù)陣的選取方法，以及被控對象模型中含有一個積分環(huán)節(jié)控制器的設(shè)計方法。
The symmetric values about the imaginary axis of zero-poles which the unstable process lies in the open and closed right-half plane are defined as their mirror-injection.
非穩(wěn)定過程在開右半平麪的零極點關(guān)於虛軸的對稱值稱爲(wèi)該零極點的鏡像映射。
The geometrical concept is to make a lot of parallel lines of the imaginary axis in the complex plane, and to decide the points which satisfy both the root loci and the parallel lines by the computer.
其幾何意義是，在複平麪上作一系列平行於虛軸的直線，用計算機求解這一系列直線與根軌跡的交點。

And, as Euler's successor, Carl Friedrich Gauss, was to discover, if you plot real numbers on one axis of a graph and imaginary ones on the other, you create a plane that represents both sorts of numbers.

Complex numbers, which have a real and an imaginary part added together, are the points on this plane that do not lie on either axis.
