An adaptive attitude fusion algorithm based on accelerometer model reconstruction is proposed to solve the problems of slow convergence
difficulty in determining step size and big impact of non-gravity acceleration.On the basis of the accelerometer model reconstruction
adaptive Momentum gradient descent algorithm is used to fuse the data from gyroscope and accelerometer
then the horizontal attitude angle can be obtained. Finally
the yaw angle is calculated by the obtained horizontal attitude and the magnetometer data. The experimental results show that the precision of the proposed algorithm is improved by 3~4 orders of magnitude and 1 order of magnitude
respectively
compared with the traditional algorithm at low speed and high speed.
