Convert m-code into state space block

I'm trying to convert a feedback control system that I've implemented in M-code into a Simulink model.

In the code, I used the 'ss' function and 'lsim' to obtain results.

However, even though I input the same state equations and control inputs, the results diverged when using a state-space block in the Simulink model.

I'm wondering if anyone has experienced a similar issue and if I could get some assistance with this. Have you ever encountered a situation like this?

Hi @Junghyo Kim

Could you please attach the m-file by clicking on the paperclip icon ?

Alternatively, you can copy and paste the MATLAB code. Click on this icon to enable the Code mode (grey field).

paste the code

Actually, I resolved the issue by reconfiguring the sampling time.

Thank you so much.
