Comparison of Multirotor Wind Estimation Techniques Through Conventional On-board Sensors

Research output: Contribution to conferenceConference Paper

Abstract

This paper compares three approaches to measuring local wind speeds using multirotor vehicles through the conventional sensors regularly found on board. The three methods being compared in this work are firstly, a model developed through comparison of measured wind speeds and body angle of the vehicle in the hover condition. Secondly a novel approach to modelling through manoeuvres allowing wind estimation without the need for any external wind sensors to be present during modelling. Finally a modelling approach based on wind tunnel data of the airframe and propulsion system under a range of wind speeds, motor settings, and angles. These three approaches are described and developed then flown to gather data for comparison against a static WindSonic anemometer at an altitude of 10m. This is then developed upon by comparing the accuracy of the models in steady state climb conditions. Developing the capability for multirotor based wind estimation using the sensors found on-board most vehicles reduces the need for additional sensors in an often already limited payload. This could help to improve the operational capabilities of multirotor Unmanned Aerial Systems (UAS), and be a useful tool in the future of weather forecasting and operational decision making.
