Improved Path Planning and Attitude Control Method for Agile Maneuver Satellite with Double-Gimbal Control Moment Gyros

Abstract EN

Double-gimbal control moment gyros can implement the satellite attitude maneuver efficiently.

In order to reduce the energy consumption of double-gimbal control moment gyros and avoid the singularity state, an attitude maneuver path planning method is proposed by using the improved Fourier basis algorithm.

Considering that the choice of the Fourier coefficients is important for the Fourier basis algorithm to converge quickly, a choosing method of the initial Fourier coefficients which can reduce the computational time of the path planning algorithm notably is proposed.

Moreover, an attitude-tracking feedback controller based on the Fourier basis path planning algorithm is designed to acquire robustness.

Simulation results show that the proposed path planning algorithm can implement attitude maneuver path planning in shortened time.

Meanwhile, the feasibility of the attitude-tracking feedback controller which is based on the above path planning algorithm is verified in terms of the low energy consumption, high attitude-tracking precision, and the safe use of double-gimbal control moment gyros.
