s-function Can't be Linearized ?

Hi everyone,
I have built a non-linear model in MATLAB, and I have been able to reproduce it in SIMULINK using level 2 s-function. The next step in my project is to implement an MPC controller to control the dynamics of the model. Unfortunately, it seems from my small research that the s-function is not defined as an LTI system and the linearization of the model can't be done. Does anyone have a solution or workaround to this problem?
Thanks,
P.S. I have tried to use the MATLAB function block but I haven't known how to interpret the continuous-time of the SIMULINK inside the function properly.

Then try using your hand-linearized model on the MPC for design purposes.
Once completed, hook up MPC back to the S-function model.

The problem is that I have a system with multiple units, the one that I can linearize it is easy but the others ....
I'm looking for an all-in-one solution where I don't need to deal with the hastle of linearizing each unit within my system.
BTW, thanks for suggesting this idea.
