Hi, any body is having answer for following problem:
I am Getting different results while simulting Step response for simple transfer function g= (23.2)/(0.13 s^2 + s) in matlab code and simulink with PID controller (p=1.4175e+03 i=1.5559e+03 d=158.1210). I have attached both results: Fig1 by using matlab step command for plant and controller, whereas fig2 for simulink with same plant and controller.

Sadeep, Fig 1. looks very much like the step input (rather than the step response). Compare this figure to
g = tf(1,1)
g =
1
Static gain.
step(g)
Please post your MATLAB code so we can help.
