pole placement in arduino

hai, i have manage to have PID controller in my arduino system to control voltage using PWM. I have intent to apply pole placement. Do you have some example of coding or system? thank you,.

Sorry, but your question makes no sense to me. Can you please explain exactly what you are trying to do ?

A pole is an infinity in the transfer function of a digital filter. A PID is simply a specialized digital filter.

So what transfer function do you need?
