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

You just need to enlarge the block

uhhuuuu! thanks

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?

[Setsuna Yuuki.]

send me your simulation file, to better see the problem.

[Joaquim Lima]

ok

Please thank

Good Morning ! did you see the code?

[Setsuna Yuuki.]

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.

has a solution?

what is another block?

[Setsuna Yuuki.]

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?
