多星发射上面级主动抗扰姿态控制技术研究
Study on Active Disturbance Reject Attitude Control Technology of Multi-satellite Upper Stage
摘要
Abstract
For the issue of severe coupling attitude control of multi-satellite upper stage for sub satellite deploying,an improved predictive functional control (PFC) based on generalized extended state observer (GESO) is presented in this paper.All the structure parameter deviations of upper stage and induced disturbance torque that are resulted by centroid eccentricity,companied with system parameter deviation,external disturbance and unmodeled dynamics can be regarded as a lumped disturbance.This mismatched disturbance is converted into matched disturbance with equivalent-inputdisturbance (EID) technique,and then estimated by GESO as well as the transformed system states in an integrated manner.The estimated lumped disturbance can be eliminated in a negative feedback loop,which promises that the predictive model always matches the real upstage dynamics model and further provides PFC with precise tracking,fast response,as well as strong robust against external disturbance and parameter deviation.A simulation example and a comparison with some prominent methods in the presence of significant disturbance and parameter uncertainty demonstrate the robustness and effectiveness of the proposed method.关键词
