PID controller doesn't do anything after tuning #5

Closed RubenKelevra closed 2 years ago

I'm trying to use the PID controller to control the fan speed of my air cleaner.

So the output is 0 to 3.

The input is a particle sensor in the same room.

I've followed the tuning instructions and came out with 0.2 over swing on the input and a delay of around 60 seconds.

But configuring these values will result in a 0 on the output all the time.

My settings:

The status of the controller:

In the last 2 hours you can see the output of the controller at 0 while the setpoint of 12 was exceeded over long durations:

Did I miss something? 🤔

From what I see your source at the moment is "33,42" and you are targeting "17"! The PID by default will raise the value, so if your ideia is to use the pid to take the value from "33,42" to "17" set the option "invert" to true.

A better way to tune the PID is to use "input_number" to change the values on the fly.

Well invert is on.

But I saw your fix for invert PID and since I've installed this version it works as expected.

Thanks for the fast fix :)
