Simulink MPC Controller Constraints

I am designing an MPC controller in Simulink, the plant has 3 manipulated inputs and 2 controlled variables.

The plant also has 4 additional measured variables which I would like to use as constraints. My question is, how do I make the measured constraints available to the MPC controller? Do I need to make them controlled variables and give them a nominal reference?

Hi James,

By "controlled variables" I am assuming you are referring to measured outputs. I believe that with linear MPC you can only specify constraints on measured outputs, so the 4 additional variables you mentioned should be converted to measured outputs.

With nonlinear MPC you can set constraints to both outputs and states.
