Implementing a PID Controller Can be done with analog components Microcontroller is much more flexible Pick a good sampling time: 1/10 to 1/100 of settling time Should be relatively precise, within 1% use a timer interrupt Not too fast variance in delta t Not too slow too much lag time Sampling time changes relative effect of P, I and D Input/Objective Output/Result. General guidelines to formulate such a control-oriented model encompass the following six steps at least: 1. Identify the system boundaries (what inputs, what outputs, etc.). 2.
