PID Control with Dynamic Disturbance Compensation

  • Entry
  • Associated product(s)
Objective of the Application is fast and tight control of processes affected by strong disturbances. Thereby the disturbances must be known and measurable.

Objective of the Application
The implementation and the potential for improvement in comparison to a conventional PID controller will be shown with the “APL_Example_EU”.

Main contents
The following main points are discussed in this application note:

  • How to create an instance of the process tag type
  • How to collect the necessary measurement data for modelling
  • How to identify the relevant models with the MPC configurator
  • Benchmark simulation with and without disturbance compensation, to show the potential benefits

This entry was created with SIMATIC PCS 7 V7.1, the procedure is transferable to PCS 7 V7.0 SP1 and higher versions.
