Hi, to reduce vibration balancing the propellers and motor rotors may help. We found that sometimes the motor rotors are the main source of vibrations. With motors an propellers out of the box i found vibrations in the rate signals in the range of 30% of the measuring range. If the system is well balanced the value is in the 5% range. Adding a low pass filter (15..50Hz) to the acceleration signal may also help. Low pass filtering of the rate signals below 100Hz results in instability. Heinrich Loic Drumettaz schrieb: Hi, |
