Conclusion the actual process is not first order but is represented by (Ks + Cs^2)/s^2

Bro but my tcr ask to explain like why the two graphs are different why the lines arent rhe same . My tcr said explain througg words leh

The graphs are different because the actual process is not first order, hence the theoretical output is different from experimental output.

I do not think it can be explained just with words, we need some derivations to show why it is so.

The best you can say is the actual output varies linearly with time, and the Laplace transform of this linear function shows the actual process has second order poles and zeros transfer function.

Bro you told me it is step response for first order and I thought the difference is in the process not the response.

When are you going to present? Actually I am still unclear on the question. You are given an experimental and theoretical graphs, and you are told the process is first order? What other information were provided?

Unit ramp input to a first order process gives a linear y(t) response, while a unit step input to a first order process gives an exponential y(t) response.
