Autorotate, SystemID?

For Arducopter quadrotor, what do these two flight-modes do? I googled it and searched forums, didn’t help, so please forgive my ignorance.
Thanks in advance.

  • Autoratate is for traditional helicopters. Just google for “Helicopter autoratation” and you will find out what it is.
  • SystemID is for mathematical model based system identification. You need to know about control theory to understand this one. Not meant for normal users without technical background knowledge.

To add some more detail, here’s the wiki page for system-id. Hopefully we can eventually fill out the wiki with more information on how the outputs from this “system identification mode” can be used to improve tuning.

I’ve added a wiki to-do to explain auto-rotation. Maybe we should add, “(Heli only)” so that normal users can quickly know that this isn’t for them.

I knew about it on traditional helis, couldn’t figure out how it applied to multi-rotors though. Thanks for the info.

@rmackay9 is there any progress on version based wiki pages?

The changes for 4.0 will confuse a lot of 3.6 users.


There’s some good progress on making version based parameter descriptions on the server side (PR).
