I am currently working (searching for the moment) on a way (simulator) to figure out "basics PIDs" for any (common) multicopter on PX4. I work on big X8 multicopter and I don't want to go from scratch and crash the drone...
I think, I am not the only one who want to have an idea of the basics PIDs to fly normaly. Somenone are searching for the best PIDs from theoretical calculation but I think it is impossible, you always have to play with the PIDs value to aprroach the perfection... But just for basics it's seem to be possible.
With the DJI A3, no PIDs... You just have to choose the right frame size, the rates and it calculate the best PIDs depend of the condition, very impressive. I think, in the futur, PX4 will offer the same is just a mater of time! I red about MPC regulation with it we will forget the PIDs (...)
I did some research but i don't find something interesting for the moment:
- FlightPlot : You have to flight one time before check the values.
- PX4 dev kit for simulink : I do not find any information about simulation.
What I am looking for is simple. You enter the mecanical parameters of the drone (frame size, motor configuration, prop size, etc...) and the simulator give basics PIDs to have a secure fly. Does it exist ?
If I don't succed to find it, does it mean that, with PX4 there is an other way than simulation to have basics PIDs ?
If someone have some info ? I continue my research !
