MPC cannot be designed in app

I have a Carsim S-functon as the plant model for a MPC. But I get an error saying "Plant model cannot be a pure direct feed-through system without additional dynamics". Why does it keep saying that?

I have the same problem, do you have a solution already?

@Pengshan Dai I didn't. Please share the solution if you get it.

The compatibility between CarSim and Simulink is not high,if you have the state space,you should use it,or you only choose the s-function to make it.

Hey, thanks for the reply. I do have the state-space, but I also want to capture the non-linearity and actuators delay which are difficult to model. Plus, I wil have no way to verify since I don't have actual vehicle data. Since Carsim is a high fidelity simulator I chose it. I didn't get the last thing you wanted to say.
