We recently converted an old MPC SISO application from an "MPC" block to an "MPC Pro" block. It's working better than the old block, which was having issues with unmeasured disturbances. These same disturbances are causing some cycling with the new MPC Pro block.
When building the controller from a model (in "Expert" mode at least) there's a slider for "Robustness / Performance" in the "Predict" (model & controller building) application. I assume this one has some effect on the "gain" or aggressiveness of the MPC Pro controller. What about the slider in the "optimizer"? If I have an SISO application with an objective to "maintain setpoint" does the optimizer have any impact on how aggressive the response is?
Any thoughts on how to "tune" MPC Pro for a integrating CV for feedback control of unmeasured disturbances would be welcome.
Best Regards,
John
