tikz를 사용하여 제어 다이어그램을 그리려고 하는데 이에 관해 몇 가지 질문이 있습니다.
- 교란으로부터 경계를 어떻게 제거할 수 있습니까?
- 비용 및 제약 조건 노드를 왼쪽 및 오른쪽 위치에 어떻게 배치할 수 있습니까?

하려면 어떻게 해야 합니까?u(n)
위의 결과로 다음을 시도했습니다.
\draw [->] (y) |- node [near end] {$y(n)$} ($(predict.east)+(0,0.35)$);
\draw [->] (u) |- node [near end] {$u(n)$} ($(predict.east)+(0,-0.35)$);
답변1
draw=none
. 아니면 테두리를 그리지 않고 새 노드 스타일을 정의하시겠습니까?원하는 결과에 따라 여기에는 많은 가능성이 있습니다. 예를 들어 앵커, 교대를 사용하여 위치 조정을 미세 조정할 수
below right
있습니다 . 라이브러리가 로드된below left
경우positioning
다음과 같은 것을 사용할 수 있습니다below left=10pt and 20pt of <name>
(아래 두 번째 예제 코드 참조).

원래 질문을 편집한 후 새 질문의 경우 첫 번째 레이블의 노드 중 하나에 이름을 지정한 다음 수직 좌표계를 사용하여 다른 레이블을 동일한 x 좌표에 배치하는 것이 아이디어입니다. 다음 예제 코드는 이를 보여줍니다.
