Características Generales

 
  • Para el caso de Studio 5000, esta aplicación utiliza un bloque de proceso Lead-Lag.

    Con esto lograremos simular el comportamiento de un sistema de control de temperatura

Paso 1
 
 

Guía de implementación para Studio 5000.

Crear una Tarea Periodica.

Para este ejercicio se utiliza un Trigger de 10ms pero este tiempo puede ser ajustable de acuerdo al tipo de proceso que se quiera simulara.

Paso 2
 
 

Crear una rutina del tipo Function Block Diagram.

 

pid-simulation-with-lead-lag-and-1st-order-filter_Fig 6.png

pid-simulation-with-lead-lag-and-1st-order-filter_Fig 6

Paso 3
 
 

Insertar las instrucciones de PID y LDLG como se muestra a continuación.

 

pid-simulation-with-lead-lag-and-1st-order-filter_ Fig 7.png

pid-simulation-with-lead-lag-and-1st-order-filter_Fig 7

Paso 4
 
 

Sobre la linea que conecta la salida del bloque LDLG hacia el PV del PID, dar click derecho y seleccionar “Assume Data Available”.

Este es un paso importante ya que de otra forma el controlador marcará un Error debido a que no puede resolver el bucle formado entre estos dos bloques.

Paso 5
 
 

Ajustar los parámetros y ganancias del PID acorde al proceso que se desea simular.

Conclusión
 
 

Con esta parametrización se logra un comportamiento de un sistema Sub-Amortiguado  con  sobre impulso de aproximadamente el 20% y alcanzando una estabilidad en tres semiciclos.

Pero se puede ajustar para obtener cualquier comportamiento deseado de acuerdo al proceso que se desea simular.

 

0 < ζ < 1  Sistema Subamortiguado
ζ = 1  Sistema Criticamente Amortiguado
ζ > 1  Sistema Sobreamortiguado
