摘要	To use effectively the magnetic compass in a multi-rotor Unmanned Aerial Vehicle (UAV) in special environments, this paper researches the magnetic deviation correction method when it works at a large current and a variable control amount. Firstly, the variation patterns of magnetic deviation were derived and an error model was established. The relationship between hard magnetic error and the control amount was also analyzed. Then, a spatial linear fitting method was proposed based on Total Least Square (TLS). Finally, the relationship between hard magnetic error and control amount was adopted to implement the hard magnetic compensation of the UAV. In this way, the magnetic deviation was adaptively compensated and the compass was corrected in real time. Experimental results indicate that the hard magnetic deviation from the changed control amount can be counteracted by proposed method, and the yaw error of the UAV reduces from 15 to less than 3 during the flight. It concludes that the method proposed in this paper effectively corrects the yaw error of the magnetic compass when it works at the high current and large control amount and the navigation accuracy and capability to variable loads of the UAV is improved greatly. 2016, Science Press.
