An aeromagnetic compensation algorithm for aircraft based on fuzzy adaptive kalman filter

In order to ensure the effectiveness of geomagnetic navigation,as the foundation,the precise measurement of geomagnetic field must be guaranteed; namely,aircraft aeromagnetic compensation is worthy of being further studied. in this paper,the classical aircraft aeromagnetic compensation algorithm based on leliak model is analyzed and an aircraft aeromagnetic compensation algorithm based on fuzzy adaptive kalman filter is proposed,which is a new approach for aircraft to achieve aeromagnetic compensation. simulation results show that it has better compensation performance without relying on the aircraft attitude. copyright © 2014 yao zhang et al.
