what is a pid?
Just to get it out of the way, PID stands for âProportinal, Integral, Derivative,â and has to do with how the controller does what it does. Rather than go into that level of detail, this page is going to focus instead on the results of using PID control. If youâre interested in reading more about the inner workings of PID, the wikipedia article is quite detailed. Letâs get started. An easy to explain what PID control is, is to first look at what it isnât. If you were to graph the temperature in your home oven, it would look something like this. You can see that weâre asking for 325, then 350 degrees. The actual temperature cycles above and below these values.
