When a transfer function is determined from a plant model for a control system. If Laplace transforms are used does one apply the PID equation (position or velocity) to the transformed plant directly or does it have to be converted back to the time domain?
Also does one have to take the difference of equations to dynamically asses the error term? I'm trying to avoid the standard "cookbook" PID code and get something that is specific to my system being measured (temp controller). Any clarification on this manner would be greatly appreciated.
