"Very interesting work!

What about after applying your custom temperature compensation, which of the barometers would you recommend?

I ask because the LPS25HB has a less noise(0.03/0.01 mbar rms) and accuracy compared to the MS5611 (+-0.05mbar), on…"

"Thanks :).

I used microsoft visual studio and it was done in C#. I reused objects such as the instrument panel from the old GSC that was used here at DIYdrones (Happykillmore)."

I can't seem to find a reference to the control architecture of the ArduCopter. Does anyone know where i can find one (if it exists).Also, does anyone know at what (typical) frequencies the feedback loops for the attitude control run at?Thanks,Alex

"Fuzzy logic is a different control method which translates "human intuition" into approximate feedback gains.
 
It’s more suited when you lack a (accurate) mathematical model of the plant, but you know how to manual control it.
 
As for controlling…"

"Nice work. Did you consider using the system identification tool from matlab (if you have it)?
If you have some raw input - output data i could give it a go myself and see what kind of transfer function i can compute. It doesn't need to be an…"

"The book focuses entirely on the FreeRTOS API, and is not really focused on the STM32 itself. The FreeRTOS comes with an entire library of different ports (for different MCU and compilers), and the STM32 Cortex M3 is one of them. Implementing into…"

"@ Mark, I'm the first to say that the current AHRS is too expensive ;). The VN-100 was used as it provided an easy to use and robust sensor which allowed the project to be completed in the short time frame that was fixed. the next step is indeed to…"

"thanks you all for the kind words.
 
Thanks again to Paul Mather for your gsc, as you can probably tell it helped speed things up quite a bit ;). As for selling the board, there are still small changes I'd like to make and features to add as well as…"

Hello all.I've been a long time lurker on this website, checking it almost daily. The last couple of months i was working on my bachelors project which consisted of designing from scratch an autopilot for a RC glider. During that time, this website…
