Linearizing power system model for model predictive control

Hello,

I have a simulink model of discrete load frequency controller for a micro hydropower system.. It is used to regulate the frequency of the grid due to load changes.

The model uses a discrete PD controller to control the secondary load (dump load).

Currently I want to develop a model predictive controller but i have a hard time to linearize the model. I hope someone can help me on this matter. I have tried the system identification toolbox using input and output data but not successful.

I hope someone can advise me on this matters.

firstly, get the state-space model of the system. And then try using linmodv5 command. Might do some help.
