This is how we all should tune in our copters...

Happy New Year to everyone!

I found this articles while searching methods for effective PID tuning:

The method is described here:

and here:

Have a happy year 2012!

  • I agree with you, Alfred. The pivot should be somehow fixed solidly to allow higher thrust levels.

    Meanwhile after some reading about this Ziegler-Nicols-Method, I find it only half usefull.

    One good thing is: your get familiar with PID-Systems. Another good thing is that you find the Pmax for your copter.

    The disatvantage of this method seems to be, that it's very theoretical and real life always differes from theory...

    So I found another very good tutorial that shows a very practical way of tuning in PID-values for stabilize and rate modes:

    This seems to lead in the right way by understanding the theory and transfering it into reality.



  • I kinda like this in general. I don't like that it is unrestrained. If the pivot axis was mounted firmly then I would feel more comfortable applying power and control inputs. I can see where it would allow quicker pid adjustments if it was connected to the computer while testing.

  • Dont forget this :


    1:Experiment can be time consuming

    2:Can venture into unstable regions while testing the P controller, which could cause the system to become out of control

    I do some pid tunning using this metod some year ago and i can SAY: Its very dangerous.

    Take too much care with this metod is you not know anything about PID.

    Attach the copter to a gimbal to make this.
