Experimental Research on UAV Stability based on Vibration Signal Measurement of UAV Motors

The UAV flight practice shows that there is correlation between motor vibration and UAV stability, in this paper, a UAV stability lost accident has been taken seriously, the UAV motors are measured carefully, and the characteristics extraction of UAV motor vibration signal is used to analyze the correlation quantitatively. The analysis results covert the time domain signal into frequency domain for more intuitive presentation, and the positive effect has been further proofed. The analysis method proposed in this paper could prevent UAV motor vibration from resulting more damage to UAV.
