Abstract
A major application case for drones is its usage as a flying video camera. Vibration excited by motors and wind reduces the video quality. Therefore passive and active vibration reduction mechanisms as electromotor enhanced gimbals are typically integrated. By means of these measures a good vibration reduction can be achieved. Nevertheless in certain operation conditions, still a reduced video quality is observed. As a typical phenomenon the rolling shutter effect is observed. This work presents the positive effect of a device for an active vibration reduction of a camera mounted on a quadrocopter. It focuses on the experimental identification of the vibration behaviour of the quadrocopter in different defined flight conditions. The effects of vibration excitation by wind and electromotors onto the acceleration of the camera are presented. According to the results an active vibration control system based on an electrodynamic actuator and velocity feedback is designed, realized and tested on test rig and in flight.
