What is the N coefficient filter in simulink? What effect does it have on the PID controller?

Hi Rikke,
Please refer to this post:
The filter coefficient is used to implement derivative action. Since implementing something like "Kd*s" is not possible since implementing improper transfer function is not possible. Hence instead of "Kd*s", we do something like:
Kd*(N*s/(s+N)).
So if N is sufficiently large, it tends to "Kd*s"
Hope this helps.

Hi Vaibhav, I have the following question: how can implement in Simulink a PID expressed like this? I'm not able to put it in Simulink's form. Thanks for your help,

Can I give filter cofficient as N=2000, which will giving good indcutor current response for my buck converter, rather than using N=100(which will producing more noice)
