Abstract EN
Based on the temperature drift characteristic of fiber optic gyroscope (FOG), a novel modeling and compensation method which integrated the artificial fish swarm algorithm (AFSA) and back-propagation (BP) neural network is proposed to improve the output accuracy of FOG and the precision of inertial navigation system.
In this paper, AFSA is used to optimize the weights and threshold of BP neural network which determine precision of the model directly.
In order to verify the effectiveness of the proposed algorithm, the predicted results of BP optimized by genetic algorithm (GA) and AFSA are compared and a quantitative evaluation of compensation results is analyzed by Allan variance.
The comparison result illustrated the main error sources and the sinusoidal noises in the FOG output signal are reduced by about 50%.
Therefore, the proposed modeling method can be used to improve the FOG precision.
