I'm having a problem with the PID control

when I'm using The PID controller block it works fine but, when I use the Math/derivative/integral the derivative is not working and it is giving an error, can anyone help me with this

Please open PID controller block and post a screenshot showing its parameters.

You will see "filter coefficient N". Ideal derivator is non causal system. So if your differential gain is Kd, instead of using du/dt block, you will have to use something like this:

The PId controller is fine, and I'm using the same parameters as the Gains blocks

my problem is when I'm using the Dericative block it shows this error

When you use derivative block, you have to use filter coeff N as well in order to mimic PID controller that is in the std library.

This is what you need to implement in the derivative branch:

This is what is equivalent to PID controller derivative part.

Thanks a lot iy is working now after adding filter coeff, btw I didnt see the part of the comment about the N coeff
