Say you have an arbitrary mpc object from the MPC Toolbox.
It has the following property: mpcobject.Weight.ECR which is set to 1*10^5 by default. On the MATLAB documentation page (see: https://de.mathworks.com/help/mpc/ug/specifying-constraints.html#buj077i ) it says that it is an "overall constraint softening parameter of the controller (controller object property: Weights.ECR) to penalize a tolerable soft constraint violation relative to the other cost function terms".
However, I dont understand what that means. I’ve already specified ECR values for their respective OV/MV’s.
How can a single ECR value be used to penalize a soft constraint violation relative to multiple cost function terms?
What happens when I just leave it at 1*10^5? Does this effectively change the resulting ECR value of each OV/MV’s?
What happens when I set it to 0 or 1?
Thanks in advance :)Say you have an arbitrary mpc object from the MPC Toolbox.
