numerator , denominator, Transfer function,Equation

Good afternoon! how do i enter the equation as mentioned in fig. 1 of the transfer block?
In the transfer block of fig. 2?
I try to insert the equation but it appears in num (s) and den (s), I need it to be as in fig. 1
Attached figures
Equation
1.077e04
-----------------
3.439e-07 s ^ 2 + s

You just need to enlarge the block

Hello!! Thanks for reading my posts, please I have a problem, as shown in the figures below.
I am not able to generate the optimal curve in Simulink fig1, as in the example of simulink fig 2?
where am i wrong?
send me your simulation file, to better see the problem.
Good Morning ! did you see the code?
I think that difference between your simulation and the other simulation is the PID controller. I tried with your transfer function, but got the same result.
The other block is a PID controller, and has its own parameters, those values must be calculated with some method.
Method of calculate PID controller --> Ziegler Nichols (It's not the only one)
This controller combines the P (proportional), I (integral) and D (derivative) controllers.
More info --> PID controller
All these are automatic control concept.
ok, but which one do I use to get the curve?
I'm screwed, I have a week to deliver my final assignment.
Do you know what I need to do?
My name and Joaquim, I live in São Paulo, study at UFABC
