Anpassen von System objects für Simulink
Anpassen von System object™ für die Verwendung in MATLAB System-Blöcken
Der MATLAB System-Block ermöglicht die Verwendung eines in MATLAB® definierten System object als Block in Simulink®. Verwenden Sie zur Anpassung Ihres System object die bereitgestellten Implementierungsmethoden, um das Aussehen oder die Ausgabe des Blocks zu steuern oder die Verwendung von System object in einem Subsystem zu ermöglichen. Weitere Informationen zur Definition eines System object finden Sie unter Define Basic System Objects oder System Objects.

Überblick
- Define System Object for Use in Simulink
Develop MATLAB System block and interactively preview block dialog box. - System Design in Simulink Using System Objects
Design systems in Simulink using System objects. - Simulink Engine Interaction with System Object Methods
Follow a process view of the order in which the MATLAB System block invokes System object methods within the context of the Simulink engine. - Considerations for Using System Objects in Simulink
Consider these guidelines when working with variable-size signals, tunable parameters, and For Each subsystems.
Aussehen eines Blocks
- Customize MATLAB System Icon and Dialog Box Using Mask Editor
Customize MATLAB System block appearance using Mask Editor graphical user interface.
Eingabe und Ausgabe
- Set Model Reference Discrete Sample Time Inheritance
Disallow model reference discrete sample time inheritance for a System object. - Use Global Variables in System Objects
Define global variables for use in System objects. - Specify Output
If Simulink cannot infer the System object output characteristics, add methods to specify the size, data type, complexity, or discrete state output. - Add and Implement Propagation Methods
To define output specifications, use propagation methods.
