모델 상호 연결

직렬 연결, 병렬 연결 및 피드백 연결(블록 다이어그램 작성)

구성요소의 모델을 상호 연결하면 제어 시스템의 모델을 생성할 수 있습니다. 피드백 구성에서 연결된 플랜트 및 제어기와 같이 여러 상호 연결된 구성요소를 포함하는 블록 다이어그램으로 제어 시스템을 개념화할 수 있습니다. 모델 산술 또는 상호 연결 명령을 사용하여, 이러한 각 구성요소의 모델을 전체 블록 다이어그램을 나타내는 하나의 모델로 결합할 수 있습니다.

Why Interconnect Models?

Interconnecting models of system components allows you to construct models of control systems.

Connecting Models

This example shows how to model interconnections of LTI systems, from simple series and parallel connections to complex block diagrams.

Numeric Model of SISO Feedback Loop

Interconnect numeric LTI models to build a single model of a closed-loop system.

Control System Model With Both Numeric and Tunable Components

Interconnect fixed components and tunable components to build a tunable control system model.

Multi-Loop Control System

Build arbitrary block diagrams with any number of control loops by interconnecting models using the connect command.

MIMO Control System

Build a MIMO control system with both fixed and tunable components.

MIMO Feedback Loop

Obtain the closed-loop response of a MIMO feedback loop three different ways.

Using FEEDBACK to Close Feedback Loops

This example shows why you should always use FEEDBACK to close feedback loops.

Mark Analysis Points in Closed-Loop Models

Insert analysis points at locations of interest when you build control system models. Use analysis points for extracting system responses from the model.

Control System with Multichannel Analysis Points

Build a control-system model with analysis points for extracting responses at different points in the system.

모델 상호 연결에 대한 세부 정보

Catalog of Model Interconnections

Block diagram connections correspond to model interconnection commands or arithmetic expressions.

How the Software Determines Properties of Connected Models

When you interconnect models, the resulting model’s properties depend on the properties of the models you are connecting.

Rules That Determine Model Type

Precedence rules determine the resulting model type when you interconnect models of different types.

Recommended Model Type for Building Block Diagrams

Choice of model type can affect numerical accuracy when you interconnect models.
