MPC Reference Dimension Simulink

I am getting an error stating that the reference should have 12 columns, but when I turn on the dimension, it is clear that the reference does indeed have 12 values. What is the issue here?

Hi Tristan,

From the error you encountered it seems like the reference signal isn’t in the right format for the Nonlinear MPC block, it should be an array where the number of columns matches the number of output variables the controller is tracking (12 columns). Adding a Transpose block between the Step block and the ref input of the Nonlinear MPC block can match the required input format.

For more information you can refer to https://www.mathworks.com/help/mpc/ug/nonlinear-mpc.html

Hope this helps!
