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.

Temas

Generalized Models

Generalized models represent systems having a mixture of fixed coefficients and tunable or uncertain coefficients.

Models with Tunable Coefficients

Use tunable models to model tunable components of control systems for parameter sampling or control system tuning.

Tunable Low-Pass Filter

Represent a transfer function with a tunable parameter.

Create Tunable Second-Order Filter

Represent a transfer function with multiple tunable parameters.

Create State-Space Model with Both Fixed and Tunable Parameters

Represent state-space matrices that have a mix of fixed and tunable parameters.

Control System with Tunable Components

Build a control-system model for tuning using both tunable and fixed components.

Control System with Multichannel Analysis Points

Build a control-system model with analysis points for extracting responses at different points in the system.

Mark Signals of Interest for Control System Analysis and Design

Analysis points allow you to access to internal signals, perform open-loop analysis, or specify requirements for controller tuning in systems modeled in either MATLAB® or Simulink®.
