Modelos ajustables

Modelos con coeficientes ajustables o paramétricos

Los modelos LTI generalizados ajustables representan sistemas que tienen coeficientes fijos y ajustables (o paramétricos). Utilice los bloques Control Design para representar componentes ajustables de su sistema de control. Combínelos con modelos LTI numéricos para crear modelos LTI generalizados ajustables. Para ver un ejemplo, consulte Control System with Tunable Components.

Puede utilizar modelos LTI generalizados ajustables para:

Modelar un componente ajustable (o paramétrico) de un sistema de control, como un filtro paso bajo ajustable.
Modelar un sistema de control que contenga:
- Componentes fijos, como la dinámica de la planta y la dinámica de los sensores
- Componentes ajustables, como los filtros y los compensadores
Ajustar sistemas de control para diseñar los objetivos que especifique, con comandos de ajuste como systune o la app Control System Tuner.
