1.3.6 Controller Simulation and Tuning
With a reviewed model in hand, the initial controller manipulated and controlled variable tuning is established. Give up criteria (ranks) are established for each controlled variable at this stage. Constraint scenarios are evaluated for proper behavior and possibly different operating modes. The detailed configuration files which permit communication between the APC controller and user’s DCS are built and reviewed.

When automated step test software is used for the plant test, some initial simulation and tuning of the application are required prior to the testing. This gauges the control performance similar to that of the APC controller for the testing mode where constraints must be relieved and a new operating point is discovered for continued testing.
