블록 안에 어떻게 그림을 그릴 수 있나요?

안티 와인드업 기능이 있는 PID 제어 블록을 구축하려고 합니다.

\tikzstyle{controller} = [draw, fill=blue!20, rectangle, 
    minimum height=3.5em, minimum width=6em]

\tikzstyle{subblock} = [draw, fill=blue!5, rectangle, 
    minimum height=3.5em, minimum width=6em]

\tikzstyle{pidblocks} = [draw, fill=green!5, rectangle, 
    minimum height=3.5em, minimum width=6em, text width= 6em]    

\tikzstyle{transformation} = [draw, fill=red!5, rectangle, 
    minimum height=3.5em, minimum width=6em]      

\tikzstyle{filter} = [draw, fill=green!10, rectangle, 
    minimum height=3.5em, minimum width=6em]

\tikzstyle{block} = [draw, fill=windblue!20, rectangle, 
    minimum height=3.5em, minimum width=6em]    



\tikzstyle{sum} = [draw, circle, node distance=1.5cm, inner sep=0.15cm]
\tikzstyle{disturbance} = [draw=none, node distance=1.5cm, line width=0pt] 
\tikzstyle{input} = [coordinate]
\tikzstyle{output} = [coordinate]

\begin{figure}[!h]

    \begin{tikzpicture}[auto, scale=0.8, node distance=3cm,>=latex', every
        node/.style={transform shape}]      
            % We start by placing the blocks
            \node [input, name=input1] {};
            \node [sum, right of=input1] (sumofinputerror) {}; 
            \node [pidblocks, right= 5cm of sumofinputerror, yshift=1.5cm] (kp) {P\hfill$k_p e(t)$};
            \node [pidblocks, right= 5cm of sumofinputerror, yshift=-1.5cm] (ki) {I\hfill$k_i \int{e(t)dt}$};

            \node [sum, left = 0cm of $(sumofinputerror)!0.5!(ki.west)$, xshift=0.2cm, yshift=-0.8cm] (sumofantiwindup) {};

            \node [sum, right = 2cm of $(kp.east)!0.5!(ki.east)$] (controlsum) {}; 

            \node [pidblocks, right of= controlsum] (antiwindup) {};

            \draw [->] (input1) -- node[name=inputerror] {$y_{ref}(t)$} (sumofinputerror);
            %\draw [->] (sumofinputerror) -| ($(sumofinputerror)!0.5!(kp.west)$);
            \draw [->] (sumofinputerror) -| (sumofantiwindup);
            \draw [->] (sumofantiwindup) -- (ki);

            \draw [->] (ki) -| node[pos=0.95]{$+$}(controlsum);
            \draw [->] (kp) -| (controlsum);

    \end{tikzpicture}   
    \label{fig:torque_pid_block}

안티와인드업

대신 ANTI-WINDUP Symbol다음과 같은 기호를 삽입하고 싶습니다. 여기에 이미지 설명을 입력하세요

답변1

이것이 해결책입니다.

  1. \tikzset{style files}구식 정의 대신 사용하십시오 \tikzsyle.
  2. antiwindwp기호는 tikz 그리기 매크로에서 정의됩니다.
  3. PI 컨트롤러만 표시되었으므로 D 컨트롤이 추가되었습니다.
  4. 일부 코드 줄이 제거되었습니다.

업데이트간단한 메모입니다. 두 번째 대안에 대해 Claudio Fiandrino에게 감사드립니다: tikz 3.0 사용 및 다음 설정

\tikxset{mytest/.pic = {
\draw (-1,0) -- (1,0)  (0,-0.6)--(0,0.6);
\draw (-0.7,-0.5)--(-0.5,-0.5) -- (0.5,0.5) --(0.7,0.5);
}}

명령줄 사용

\pic (S) at (antiwindup) {mytest};

동일한 출력이 생성됩니다.
