Cargar datos de señal para la simulación

Cargue los datos de la señal para simular un modelo

Puede utilizar varios enfoques diferentes para cargar datos en un modelo, incluidos los siguientes:

Puertos de entrada en el nivel de raíz: importe datos de señales desde un área de trabajo, utilizando el parámetro de configuración Input para realizar la importación a un puerto de entrada en el nivel de raíz de un bloque Inport, Enable o Trigger. Para importar muchas señales a los puertos de entrada en el nivel de raíz, puede usar la herramienta Root Inport Mapper.
Bloque From File: lea los datos de un archivo MAT, y emítalos como una señal.
Bloque From Spreadsheet: lea los datos de las hojas de cálculo de Microsoft^® Excel^® o de las hojas de cálculo en formato CSV, y emítalos como una o varias señales.
Bloque Playback: cargue los datos desde el área de trabajo, un archivo o Simulation Data Inspector.
Bloques de origen: añada un bloque de origen, como Sine Wave, para generar señales de entrada a otro bloque.
Bloque Signal Editor: visualice, cree, edite y alterne escenarios intercambiables.
Datos persistentes: transmita los big data de un archivo MAT a un modelo.

Puede crear los datos de la señal de entrada en un archivo, una variable del área de trabajo o un parámetro del modelo. Puede utilizar los datos registrados en una simulación anterior, de otro origen, o crear los datos por su cuenta. Para determinar qué enfoque de carga de señales se debe utilizar, consulte Comparison of Signal Loading Techniques.
