Frequency sweeps and Bode plots

The Advanced FCS course was repeated for the second time this year. Course material was further expanded in accordance to DM recommendations including this time frequency sweep training in all axes. Data were gathered (managed to get a sample rate of 20Hz out of the flight sim which was just enough for our training purposes) and further processes. (The sweep shown below wouldn’t be the most comfortable in real conditions, but student will improve with training.)

Various FCS response types were examined and through system identification Bode plots were eventually created and analysed in class.
