Hi,

I am using Simulink to design control system for a 2x2 MIMO system. The first step for doing so is the Linearization. However I am seeing that there are two main types of Linear Analysis Points: the open loop and the input perturbation. I want to know which one of them are applicable for doing linearization at a certain simulaion instant (for eample 5 sec)? I have tested both of them but they give different results, so I am unsure which one to use. Any guidance especially about the difference between the Linear Analysis Points will be highlly appreciated as the it is not very clear from the documentation.

Thanks,

Ahmed
