Interconexión de modelos
Conexiones en serie, paralelas y de feedback; creación de diagramas de bloques
La interconexión de modelos de componentes permite generar modelos de sistemas de control. Puede conceptualizar el sistema de control como un diagrama de bloques que contenga varios componentes interconectados, como una planta y un controlador conectados en una configuración de feedback. Mediante los comandos de interconexión o aritméticos de los modelos, se combinan modelos de cada uno de estos componentes en un único modelo que representa todo el diagrama de bloques.
