摘要
在无人机操控及应用教学过程中,发现多旋翼无人机飞行时自振动噪声对飞行控制传感器控制系统造成较大的干扰,导致无人机在操控上不够精确和稳定。通过大量的研究和实践,应用压电陶瓷振子,设计三维自振动侦测单元,结合主动噪声控制技术,使由无人机自振动噪声造成的干扰得到有效减少。并提出了将压电陶瓷振子应用于无人机航拍影像稳定及录音干扰消除的新思路。
During the process of UAV control and application teaching,it was found that the self-vibration noise of the multi-rotor drone caused great interference to the flight control sensor control system during flight,which caused the UAV to be inaccurate and stable in control.Through a lot of research and practice,a threedimensional self-vibration detection unit was designed by using piezoelectric ceramic vibrators,and combined with active noise control technology,the interference caused by the self-vibration noise of the drone was effectively reduced.And a new idea was proposed to apply piezoelectric ceramic vibrators to the stabilization of drone aerial images and the elimination of recording interference.
