Hi everyone, this is my first post.

I have implemented Henrik's PID INC routine in my controller for regulating flame temperature in an external combustion chamber. The PID filter is excellent and appears to function as advertised.

Next, I wanted to characterize the plant using Simulink's PID Tuner in order to obtain as accurate as possible gain factors for P, I, and D. However, there's another variable that their concerned with called "Filter Coefficient (N)" which is part of the Derivative function in the PID Block.

Is there any example code for implementing this?
