사용자 지정 컴포넌트

Simscape™ 파일을 작성하여 사용자 지정 컴포넌트 표현

Simscape 언어를 사용하면 사용자 지정 컴포넌트를 파라미터화, 물리적 연결, 기본 방정식을 모두 갖춘 텍스트 파일로 정의할 수 있습니다. 이 페이지에 나열된 항목은 컴포넌트 파라미터, 변수 및 연결을 선언하는 방법에 대한 자세한 정보를 제공합니다. 사용자 지정 컴포넌트 정의의 다른 측면에 대해서는 방정식 항목, 이산 이벤트 및 모드 차트 항목, 복합 컴포넌트 항목을 참조하십시오.

사용자 지정 컴포넌트 작성을 시작하려면 일반적인 워크플로에 대한 개요를 제공하는 Creating Custom Components 항목을 참조하십시오. 이 페이지 하단의 "참조 애플리케이션 컴포넌트" 아래에 나열된 항목은 각 사례에 사용된 기법을 보여주는 자세한 설명과 함께 전체 컴포넌트 예제를 제공합니다.

선언 및 분기

Declaring Domains and Components
Declaration section of domain and component files: purpose, definitions, rules, member summaries.
Declare a Spring Component
The following diagram shows a network representation of a mass-spring-damper system, consisting of four components (mass, spring, damper, and reference) in a mechanical rotational domain.
Declare Component Parameters
Component parameters let you specify adjustable parameters for the Simscape block generated from the component file.
Declare Component Nodes
Component nodes define the conserving ports of a Simscape block generated from the component file.
Declare Component Inputs and Outputs
In addition to conserving ports, Simscape blocks can contain physical signal input and output ports, directional ports that carry signals with associated units.
Declare Component Variables
When you declare Through and Across variables in a component, you are essentially creating instances of domain Through and Across variables.
Define Relationship Between Component Variables and Nodes
How to connect Through and Across variables declared in a component file to the domain Through and Across variables.
Declaration Functions
Use MATLAB^® functions to compute derived parameter values or initialize variables.
