我已在上面附加了一个最小工作示例，它提供了下面的图片。

以下是我面临的一些挑战：

1. 添加来自输入 iabc 和 vabc 的三行，
2. 在 abc/dq 块中，我想要画一条对角线，并在一侧写上 abc，在另一侧写上 dq。

对代码的任何修改或必要的更新都将受到赞赏。

Answer 1

矩阵完成后，只需在 tikzpicture 内添加以下内容。

% abc/dq block
\draw[thick] (n3_3.south west) -- (n3_3.north east);
\node[below right,inner sep=2pt] at(n3_3.north west) {abc};
\node[above left,inner sep=2pt] at(n3_3.south east) {dq};
% draw three lines 
\coordinate (A) at ($(n3_3.west) + (-1,0)$);
\draw ($(A)+(-.3cm,-.5cm)$) -- ($(A)+(.1cm,.5cm)$);
\draw ($(A)+(-.2cm,-.5cm)$) -- ($(A)+(.2cm,.5cm)$);
\draw ($(A)+(-.1cm,-.5cm)$) -- ($(A)+(.3cm,.5cm)$);

有时您可能想将节点移出矩阵网格。我将下面的示例与 (n4_1) 对齐，因为它就在那里。我本来可以使用偏移距离。

% draw lines off grid
\coordinate (B) at ($(n3_3.north west)!.25!(n3_3.south west)$);
\node[inp] (C) at (n4_1 |- B) {$I_{abc}$};
\draw[connector] (C) -- (B);
