tikz 中各种块的对齐

如您所见，下方 3 个块的左侧向右移动，同时保持其右侧与第一个块的右侧对齐。

我正在使用以下代码：

\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}
\begin{document}

\begin{tikzpicture}[auto, node distance=2cm,>=latex,block/.style={draw, fill=white, rectangle, 
    minimum height=3em, minimum width=6em}]
 \node[block] (A) {$\frac{1}{sT_E}$};
 \node[circle, draw, left =of A] (B) {$\Sigma$};
 \node[circle, draw, right =of A] (C) {$\Pi$};
 \node[rectangle, below=0.5cm of A] (D) {$V_{Emin}$};
 \node[block, below=1.12 of C] (E) {$F_{EX}=f(l_N)$};
 \node[block, anchor=0.8, below=.5cm of D] (G) {$S_E(V_E)$};
 %\node[block, below right=.5cm and 1.1cm of G] (F) {$l_N=K_C\cdot\frac{l_{FD}}{V_E}$};

您随时可以覆盖默认设置。

\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}

代码解释：

  • 我在下面的三个节点中更改minimum width为。5em
  • 但是，由于节点居中，我移动了三个节点中的第一个节点。其他两个节点自动正确移动。

另一种方法是使用 TikZ 库calc（用于计算边缘的中间点）、positioning（用于定位节点）和quotes（用于边缘标签）以及nccmath包（用于中等大小的分数）。还重新定义了节点的样式：

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{calc,
                positioning,
                quotes}
\usepackage{nccmath}
\newcommand\mi[1]{\mathit{#1}}

\begin{document}
    \begin{tikzpicture}[auto,
    node distance=4mm and 22mm,
    >=latex,
    block/.style = {draw, fill=white, minimum size=9mm, minimum width=#1},
  block/.default = 16mm,
     Circ/.style = {circle, draw, minimum size=2em, inner sep=1pt}
                        ]
\node (A) [block=22mm]          {$\frac{1}{sT_E}$};
\node (B) [Circ, left =of A]    {$\Sigma$};
\node (C) [Circ, right=of A]    {$\Pi$};
\node (D) [below=5mm of A]      {$V_{E_{\min}}$};
\node (J) [above=5mm of A]      {$\mfrac{V_{\mi{FE}_{\max}}-K_D\cdot l_{\mi{FD}}}
                                        {K_E+S_E(V_E)}$};
\draw[-] (A.west |- D.north) -- ++ ( 0.6,0) -- (A)
         (A.east |- J.south) -- ++ (-0.6,0) -- (A);
\node (E) [block, below=of C |- D] {$F_{\mi{EX}}=f(l_N)$};
\node (G) [block,
           below left= 0mm of A.east |- E.west]  {$S_E(V_E)$};
\node (H) [block, below=of G]  {$K_E$};
\node (I) [block, below=of H]  {$K_D$};
\node (F) [block, at={(H -| E)}]  {$l_N=K_C\mfrac{l_{FD}}{V_E}$};
\node (K) [Circ] at ($(B |- H)!0.5!(H.west)$)   {$\Sigma$};
%
\coordinate[left=1 of B] (in);
\coordinate (aux) at ($(H.east)!0.5!(F.west)$);
\draw[->]  (in) edge["$E_{\mi{FE}}$"]   (B)
        (A)  edge               (B)
        (A)  edge["$V_E$"]      (C)
        (C.0) edge["$E_{\mi{FD}}$"] ++ (1,0)
        (E) edge["$F_{\mi{EX}}$"]   (C)
        (F) edge["$l_{N}$"]     (E)
        (F.east |- I) edge[near start,"$I_{FD}$"]   (I)
        (A -| aux) -- (aux) edge (H)
        (aux) edge (F)
        (F |- I) to (F);
\end{tikzpicture}
\end{document}
