Model predictive control toolbox implementation on dSpace board

Hi all.

I am trying to implement an MPC controller on a dSpace board. I set up the model in Simulink, but when I try to build the program, it gets past the process of linking it, but then it fails to make due to an error: ds1005 - RTI: Simstruct error: Parameter number mismatch (501).

When I use a PID controller the the make function succeeds and the code is loaded onto the dspace board.

Any help in resolving this problem would be greatly appreciated.

C.

It's more of a dSPACE question. Contact dSPACE tech support asking about that error: Parameter number mismatch (501).

Might it be possible that your MPC controller is too large to fit in, considered that you've gone through the process for a PID controller?
