Research on Aerocraft Attitude Testing Technology Based on the BP ANN

Abstract

For measure parameters of aerocraft Attitude, this paper puts forward the BP ANN model based on the information integration theory, the problem of lower angular speed accuracy and bigger navigation error are solved. Through researching the aerocraft attitude affection based on the output of the gyro/geomagnetic sensor，the network model are set up. The gyro/terrestrial magnetic sensor output signal is used as input, and real-time three axis angular speed as output. After trained for the test samples, we got the higher precision of angular speed, then calculated attitude angle applied the approximation formula method, reduced systematic errors. After lots of experiments on the no magnetic turntable, the result shows that the method has the characteristics of fast convergence and better angular speed accuracy.
