• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 MFS autopilot PID

Hello,

I've been trying to adjust autopilot PID numbers in ai.cfg(mfs 2020).
According to SDK documentation,

pid.png


They suggest setting I first leaving P and D zero.
Is this correct? I thought you always have to set P first?
well so anyway I did what they recommended,
rollPID = 0, 2, 0, 8.0, 100 rollPID = 0, 4, 0, 8.0, 100 rollPID = 0, 8, 0, 8.0, 100 rollPID = 0, 16, 0, 8.0, 100
like this.
And the airplane has absolutely no control of bank.

Am I missing something?
 
As I understand PID controllers... the P value is the primary control point. The I value is the control point that tries to reduce overshoot and attempt to flatten the "ringing". I have never had much use for the D value, to be honest.
 
"Proportional integrated delivery" control. Basically the first cruise control, although perfected in industry and military long before escaping to commercial applications. "60 MPH" would be the control point and the little vacuum cylinder moving the gas pedal probably relates to the delivery variable for that particular type of controller.
 
Also, if I remember correctly, this ONLY applies to AI aircraft so if you're trying to tune your own flight model, you're going to be out of luck.
