How to identify the Simulink Block to get State Space & Linearize SS non linear to linear SS

2 views (last 30 days)
I'm designing Model predictive controller for Automatic braking with Antilock, I'm using modified reference Model of Uncontrolled Antilock. To combine it with MPC, I met some problems in identifying the Plant (Uncontrolled Antilock), I'd like to get the s tate space from the Uncontrolled Antilock Simulink Block. because MPC need the linear MoDel process, I'd like to linearize it also. Has anyone solve those problems? How to get SS from simulink block? and also How to linearize the SS nonlinear? Hope your help as soon as possible, Big Thanks.
(I'm attaching the Uncontrolled Antilock)

You can linearize a Simulink model or a part of it using Simulink Control Design . Take a look at linearization page to learn more and see examples.
This tutorial shows the workflow well.

Thanks sir, I'll try it. But Can we get the Differential equation (Physic Model) from that Block Simulink? Would you mind to explain how to identify the unknown plant become the Diff.Equation, then, become Linear Discrete State Space?
