I want to get the non-linear state space equations of wheel block, taking the input as brake pressure and output as longitudinal slip. I want to design Sliding mode control for longitudinal slip control, therefore I need the non-linear state space model.
I have used system identification toolbox but it is giving only 6-7% best fit data which is not useful for controller design.

Hi Kartikey,
There are currently no features in the system identification toolbox that generate a nonlinear state space model from input-output data. However, if you have a state space model of the system and you would like to estimate the values of some parameters of this model, then you can consider estimating a nonlinear greybox model, please see this documentation page:
There are several examples on how to estimate a nonlinear greybox model, please see this page
