Stupid question of mine to anyone who might know about PID controllers: how does the (continuous-valued) output of the PID controller math translate to an action to take? Like, generally speaking the PID controller will say "13!" and if your actual control system has like two sliders and a binary switch, how do you know what to adjust?
@j2kun I don't know if this is a helpful answer, but honestly: It depends on the controller.
Firstly, there are two completely different ways of implementing PID, one kind of looks backwards and one kind of looks forwards, and they give very different results.
That's not even getting into the details of the implementations, the quirks of each system.
So I know I'm ducking your question in a way, but it really does come down to, your system probably operates in a way completely different from so many other systems, so there is no standard answer to a question like this.
