![使用 TikZ 绘制图块步骤和饱和度](https://linux22.com/image/423500/%E4%BD%BF%E7%94%A8%20TikZ%20%E7%BB%98%E5%88%B6%E5%9B%BE%E5%9D%97%E6%AD%A5%E9%AA%A4%E5%92%8C%E9%A5%B1%E5%92%8C%E5%BA%A6.png)
我想用 TikZ 选项创建类似此图的东西
在这里我向你展示我所知道的方法:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\usetikzlibrary{arrows,calc,positioning}
\tikzset{
block/.style = {draw, rectangle,
minimum height=1cm,
minimum width=2cm},
input/.style = {coordinate,node distance=1cm},
output/.style = {coordinate,node distance=1cm},
arrow/.style={draw, -latex,node distance=2cm},
pinstyle/.style = {pin edge={latex-, black,node distance=2cm}},
sum/.style = {draw, circle, node distance=1cm}
}
\begin{document}
\begin{figure}[ht]
\begin{center}
\begin{tikzpicture}[auto, node distance=1cm,>=latex']
\node [input, name=input] {$\pm 2.5V$};
\node [block, right=of input] (TF) {$G_m(s)$};
\node [block, right=of TF] (plant) {$0.003$};
\node [output, right=of plant] (output) {};
\draw [->] (input) -- node {$\pm 2.5V$} (TF);
\draw [->] (TF) -- (plant);
\draw [->] (plant) -- node [name = y] {$y(s)$} (output);
\end{tikzpicture}
\end{center}
\caption{TikzPicture}\label{fig}
\end{figure}
\end{document}
非常感谢大家!:D

对图片元素样式进行了新的定义:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
positioning,
quotes}
\newcommand\ppbb{path picture bounding box} % <---
\begin{document}
\begin{figure}[ht]
\centering
\begin{tikzpicture}[
node distance = 12mm,
box/.style = {draw,
minimum height=11mm, minimum width =12mm,
label=#1},
every edge/.style = {draw, -Straight Barb, semithick},
every edge quotes/.append style = {font=\footnotesize},
step/.style = {box=#1,
path picture={\draw[very thick]
(\ppbb.center) |- ++ (-2mm,-3mm)
(\ppbb.center) |- ++ (+2mm,+3mm);}
},
sat/.style = {box=#1,
path picture={\draw[very thick]
(\ppbb.center) -- ++ (-1mm,-3mm) -- ++ (-2mm,0)
(\ppbb.center) -- ++ (+1mm,+3mm) -- ++ (+2mm,0);}
}
]
\coordinate (in);
\node (n1) [step=Step, right=of in] {}; % A-2
\node (n2) [sat=Saturation, right=of n1] {};
\node (n3) [box=Motor, right=of n2] {$G_m(s)$};
\node (n4) [box=Conversion, right=of n3] {$0.003$}; % A-5
\coordinate[right=of n4] (out);
%
\path (in) edge (n1)
(n1) edge (n2)
(n2) edge ["$\pm 2.5V$"] (n3)
(n3) edge (n4)
(n4) edge ["$y(s)$"] (out);
\end{tikzpicture}
\caption{TikzPicture}
\label{fig}
\end{figure}
\end{document}
