How to do stability analysis of a MIMO simulink model?

I want to analyze a simulink model of a transmission system. I want to derive the transfer function of the system to make the analysis. But it seems to be very complicated to do so. Any approach should I follow?

You can use Linear Analysis tool in Simulink Control Design to compute a transfer function of a model (linearize the model). Take a look at this page for more info and examples. .

Hi Arkadiy, Thanks for your answer. But I can not linearize the model as it is not accepted as per customer's requirement. I have non linear elements like Lookup tables and saturation Blocks in closed loops. Any alternative solutions? Thanks in advance!

Hi @Radhakrishna Kothamasu

I am trying to do the same think. My simulink model is non-linear. Did you find out a way?

Thanks!
