Configurating of Override Control

  • Entry
  • Associated product(s)

Objective of the Application
In an override control scheme, two or more controllers have to share one actuator. Depending on the actual process conditions a switchover logic decides which controller accesses the actuator i.e. the various controllers can "override" or replace each other.
The present project example shows an application of an override control to a simulated process with two controllers. The aim of this application is demonstrating different switchover strategies with the respective advantages and disadvantages.

Main contents
The following issues are discussed in this application note:

  • Interaction of the two controllers on only one actuator, considering two different alternatives for the switchover logic and two different types of PID controllers.
  • Simulation example

Validity
Valid for PCS 7 V7.1, in principal transferable to V7.0 from SP1.
