Hi, I have been trying to reverse engineer a vehicle model and to check if I get back a similar response by creating my own model. Now, my model has got the response as expected but with a different y-axis limits. So I'm trying to change the limits as in the model's response that was reverse engineered to make the outputs seem exactly the same.

But I was not able to do that since when I changed the y-axis limits using the command- axis([xmin xmax ymin ymax]) ,I get a different response.

For instance, the y-axis limits in the response of my model is [-2 to 14]*10^-4 and the y-axis limits in the response of the model being reverse engineered is [-14 to 4]*10^-4, which is the limit I want to use for my model. Could you please help me with this.

From the plots you posted, I can see that your output and your expected outputs are different. The original plot's steady output is ~0 after time 5 secs. However, your created plots steady value is ~10e-4. Possibly, your reverse engineered model is not the same what was used to plot the original one.

I'd say recheck the equation you retrieved from Simulink and check if it is anyhow different than what you have used. If your equation and the one you obtained from simulink are same, they would result in same output.

Moreover, 'small' is a very relative term.
