Satellite attitude controller based on a multilayer feedforward network

The error between satellite attitude dynamics and its linearized model can affect the attitude control precision. The model of the error was established with a multilayer feedforward network, and a new controller based on the model and linear control theory was presented. The controller realizes the decoupled control of the satellite attitude and minimizes the state response error between satellite attitude dynamics and its linearized model in the sense of the least square criterion. Simulation results show that the control precision is high when the maneuvering angles of pitching angle, roll angle and yaw angle are all 0.01 rad.
