六旋翼飞行器平稳着陆方法研究

摘要

MWC-2012 Six rotor aircraft uses air pressure to measure its height.In the low lands,barometer has lots of measurement errors,resulting in frequent crashes.In order to overcome this phenomenon,this paper uses the ultrasonic ranging module in stead of barometer for aircraft landing height measurement.The experi-ment shows that the landing judgment on the basis of ultrasonic ranging can effectively prevent the air crash.%MWC－2012六旋翼飞行器采用气压计进行高度检测，在低空着陆时，气压计测量误差很大，造成频繁摔机。为了克服这种现象，本文采用超声测距模块替代气压计实现飞行器着陆前的高度判定，实践表明，依据超声测距进行着陆判断，能够有效防止摔机现象。
