I did a little more refining of the model from the data previously described/collected from the Pixhawk. The following are the results of System Identification and PID optimization.
The overall performance of the bank angle controller was suboptimal for our first flights. It appeared to oscillate in…Continue
The flight data was logged on the micro sd card which was plugged into the front of the Pixhawk autopilot. The Pixhawk is capable of logging various levels of data, but because the sd card used was 4gb, the default (all data logged) was chosen. It was…Continue
I took part in a research endeavor to analyze many facets of guided/autonomous parachutes…Continue
The barometric sensor alone in most cases provides noisy and drift prone measurements. I have been trying to come up with a simple way to implement a fixed gain filter to utilize the acceleration measurements from the accelerometers to help clean up the noise and also add a sanity check via sensor fusion.…
