未完成的框圖

Question

我正在嘗試複製這個框圖。

這是我目前能做的最好的事。

\documentclass[border=4pt]{standalone}
\usepackage{schemabloc}

\begin{document}
\begin{tikzpicture}
    \sbStyleBloc{thick}
    \sbEntree{E}
    \sbComp{comp}{E}
    \sbRelier{E}{comp}
    \sbNomLien[0.8]{E}{$R(s)$}
    \sbBloc[2]{reg}{$G_1(s)$}{comp}
    \sbRelier{comp}{reg}
    \sbCompSum[5]{comp2}{reg}{+}{}{+}{}
    \sbRelier{reg}{comp2}
    \sbBloc[2]{reg2}{$G_2(s)$}{comp2}
    \sbRelier{comp2}{reg2}
    \sbSortie[4]{S}{reg2}
    \sbRelier{reg2}{S}
    \sbNomLien[0.8]{S}{$C(s)$}
    \sbDecaleNoeudy[4]{S}{U}
    \sbBlocr[8.7]{cap}{$H(s)$}{U}
    \sbRelieryx{reg2-S}{cap}
    \sbRelierxy{cap}{comp}
\end{tikzpicture}
\end{document}

誰能幫我加 D(s) 輸入？

Answer 1

這似乎產生了正確的圖表。

\documentclass[border=4pt]{standalone}
\usepackage{schemabloc}

\begin{document}
\begin{tikzpicture}
    \sbStyleBloc{thick}
    \sbEntree{E}
    \sbComp{comp}{E}
    \sbRelier{E}{comp}
    \sbNomLien[0.8]{E}{$R(s)$}
    \sbBloc[2]{reg}{$G_1(s)$}{comp}
    \sbRelier{comp}{reg}
    \sbCompSum[5]{comp2}{reg}{+}{}{+}{}
    \sbRelier{reg}{comp2}
    \sbBloc[2]{reg2}{$G_2(s)$}{comp2}
    \sbRelier{comp2}{reg2}
    \sbSortie[4]{S}{reg2}
    \sbRelier{reg2}{S}
    \sbNomLien[0.8]{S}{$C(s)$}
    \sbDecaleNoeudy[4]{S}{U}
    \sbBlocr[8.7]{cap}{$H(s)$}{U}
    \sbRelieryx{reg2-S}{cap}
    \sbRelierxy{cap}{comp}
    %
    \sbDecaleNoeudy[-3]{comp2}{D}
    \sbRelier{D}{comp2}
    \sbNomLien{D}{$D(s)$}
\end{tikzpicture}
\end{document}

「D(s)」的垂直位置可以使用該行中的可選參數進行調整

\sbDecaleNoeudy[-3]{comp2}{D}
