As my first blog post in diydrones I'd like to show, specially to other noobies what is the so much talked PID so much used in our Arducopters and Arduplanes.

This video has substitles also in english and russian but you have to select it to activate them.

It shows in a very dummy but effective way what PID is, and hope it makes things more clear for…

Take a look at my heavy lift hexacopter.

It flies very stable with the standard PIDS.

Couldn't get loiter to work though.



My setup:

NTM 910kv (changed to MK3638 on 4S)

Turnigy plush 30 amp ESC

UAP 1 frame

For booms i have 12mm kite tubes

5000mah 3S (now 4S)

11x4.7

Turnigy 9x + frsky

I use the hex to take aerials, with…

If you've been wanting to understand a bit more about PID controllers, unit 5 of Sebastian Thrun's Udacity course "Programming a Robotic Car" has some nice coverage of that topic and the theory behind it.…

Hi all,

a while ago, I wrote about control structure and started a discussion. Now the discussion about PIDT1 is going on also in the "…

DISCLAIMER: This could be dangerous and might crash your copter.

OK! I made some new changes to the autotuning algorithm and I have tested it again in the simulator. I think this is ready for some real world testing from some VERY BRAVE users, or some simulation testing. Unfortunately I do not own a quad and my octo is out of commission until Tuesday, or I would be testing this right now outside.

Video of ROFL Tuning Session with spectacular crash when we deliberately detune one of the PID values! No quadcopters harmed (much) in the making of this video.  Video of stable flight below.

By the way, the ROFL quadcopter kit is still on sale on my website:…

Finally, someone has created a PID tunning howto video, from scratch to perfect stabilize flight, that I think will be very useful for the arducopter community, specially for those flying non stock frames.

The concepts are already in the AC2 PID tweaking guide developed by Jason, but a visual howto helps a lot!

 

The guide has been created by…

Hi. I have made some modifications to the MatrixPilot code to do tests on In flight tunable gain. If this is further refined, it will be possible to do tuning of P/D gains on roll, pitch and yaw axis while in flight. The idea is that the gains can be tuned with a spare button on your RC transmitter one after the other (separately) while you fly the plane in stabilized mode. The gain you want to tune is gradually increased until oscillation is seen at max desired airspeed… Continue
