A Fuzzy Neural Network Controller and Its Application Study for the Spacecraft Attitude Control System

In the field of spacecraft attitude control, the controllers based on fuzzy logic have received increasing attentions as auxiliary control strategies. A fuzzy neural network controller based on fuzzy clustering algorithm and distributed neural network is presented in this paper. This paper makes a study of fuzzy neural network controllers for the emergent satellite-ground long loop attitude control system of DFH-3 satellite, and some good results are achieved by simulations. The study demonstrates the ability to construct the heterogeneous controller from pattern data collected and the good robustness of the fuzzy neural network controller discussed above.
