Abstract EN
In order to improve the autonomy of a maneuvered GEO satellite which is a member of a navigation satellite system, an integrated design method of autonomous orbit determination and autonomous control was proposed.
A neural network state observer was designed to estimate the state of the GEO satellite, with only the intersatellite ranging information as observations.
The controller is determined autonomously by another neural network based on the estimated state and the preset correction trajectory.
A gradient descent learning method with a forgetting factor was used to derive the weight updating strategy which can satisfy the system’s stability and real-time performance.
A Lyapunov method was used to prove the stability of both the observer and the controller.
The neural network observer can reduce the influence of control on autonomous orbit determination.
The neural network controller can improve the robustness of the maneuvered GEO satellite.
The simulation results show the effectiveness of this method.
