Temas
Conceptos básicos del ajuste de PID
- Elegir una herramienta de diseño de controladores PID
Control System Toolbox ofrece varias herramientas para diseñar controladores PID. - Diseñar controladores PID con PID Tuner
PID Tuner permite realizar el ajuste automático e interactivo de controladores PID. - PID Controller Types for Tuning
Control System Toolbox PID tuning tools can generate and tune many PID and 2-DOF PID controller types.
Ajuste interactivo de PID
- Diseño de controladores PID para el seguimiento rápido de referencia
Ajuste un controlador PID para cumplir los requisitos de tiempo de subida y tiempo de establecimiento. - Tune PID Controller to Favor Reference Tracking or Disturbance Rejection (PID Tuner)
PID tuning is a tradeoff between reference-tracking and disturbance-rejection performance. This example shows how to tune to favor one or the other when using PID Tuner. - PID Controller Design in the Live Editor
Use the Tune PID Controller task to generate code in the Live Editor for designing a PID controller for a linear plant model. - Analyze Design in PID Tuner
PID Tuner provides system response plots and other tools for tuning PID controllers.
Ajuste de PID en la línea de comandos
- Diseño de un controlador PID en la línea de comandos
Ajuste un controlador PID con el comandopidtunede forma programática. - Tune PID Controller to Favor Reference Tracking or Disturbance Rejection (Command Line)
Use the tuning options of thepidtunecommand to favor reference tracking or disturbance rejection at the command line. - Diseñar un sistema de control en cascada con controladores PI
Diseñe dos controladores PI para un sistema de control en cascada utilizando el comandopidtune.
Diseño de controladores PID a partir de datos de respuestas medidos
- Interactively Estimate Plant Parameters from Response Data
If you have System Identification Toolbox™ software, you can use PID Tuner to estimate a linear plant model based on response data measured from your system. PID Tuner then tunes a PID controller for the resulting model. - Tune PID Controller from Measured Plant Data in Live Editor
Use Live Editor Tasks to generate code for tuning a PID controller based on measured plant response. - System Identification for PID Control
System identification is the process of estimating a dynamic representation of the system you want to control, based on the system response to a known excitation.
Controladores PID de dos grados de libertad
- Tune 2-DOF PID Controller (PID Tuner)
Design a two-degree-of-freedom (2-DOF) PID controller, and compare the controller performance with that of a 1-DOF PID controller. - Tune 2-DOF PID Controller (Command Line)
Design a two-degree-of-freedom (2-DOF) PID controller, and compare the controller performance with that of a 1-DOF PID controller.
Realización de ajustes en Simulink
- PID Controller Tuning in Simulink
You can tune the gains of PID Controller blocks to achieve a robust design with the desired response time using PID Tuner. - Design PID Controller Using Simulated I/O Data
This example shows how to tune a PID controller for plants that cannot be linearized. - Design PID Controller Using Estimated Frequency Response
When your plant cannot be linearized, you can estimate a plant model using frequency response estimation and import the plant model into PID Tuner.
