Conversión de tipos de modelos

Cambie la representación del modelo, por ejemplo, de un modelo de espacio de estados a una función de transferencia

Puede convertir un modelo de una representación a otra con el comando de creación de modelos del tipo de modelo objetivo. Por ejemplo, conviértalo en una representación de espacio de estados con ss y conviértalo en un PID de formas paralelas con pid. Para obtener información acerca de cómo convertir en un tipo de modelo concreto, consulte la página de referencia correspondiente a dicho tipo de modelo.

Conversion Between Model Types

You can explicitly convert a model from one representation to another using the model-creation command for the target model type.

Switching Model Representation

This example shows how to switch between the transfer function (TF), zero-pole-gain (ZPK), state-space (SS), and frequency response data (FRD) representations of LTI systems.

Convert From One Model Type to Another

This example shows how to convert a numeric LTI model from one type (pid) to another type (tf).

Get Current Value of Generalized Model by Model Conversion

This example shows how to get the current value of a generalized model by converting it to a numeric model.

Decompose a 2-DOF PID Controller into SISO Components

This example shows how to extract SISO control components from a 2-DOF PID controller in each of the feedforward, feedback, and filter configurations.

Sensitivity of Multiple Roots

This example shows that high-multiplicity poles have high numerical sensitivity and can shift by significant amounts when switching model representation.
