The Report of the Multi-Scale Filtering and Control for Spacecraft Orbital Transfer
Abstract：The report presents the research background， significance and basic theory， and summarizes the study results this year. Based on former results， we study around the seven aspects： the robust control basic theory of the spacecraft， the robust integrated translational and rotational control for spacecraft， the cooperative control for spacecraft formation flying， the motion estimation of spacecraft based on the nonlinear filtering， the robust fault-tolerant control for spacecraft， the robust orbital control for spacecraft and the robust attitude control of spacecraft. In the section of robust control basic theory， we summarized the results on the stabilization of the linear system with input delay and state delay， stabilization of time-varying linear systems via Lyapunov differential equations， the higher-order truncated predictor feedback for linear systems with input delay， L∞ and L2 semi-global stabilization of continuous time periodic linear systems with bounded controls， some results on the constrained state filtering， explicit solutions to one class of Sylvester equation， etc. Some results on the robust integrated translational and rotational control for spacecraft rendezvous and space interception are summarized in the section of the robust integrated translational and rotational control for spacecraft. The results on 6-DOF robust cooperative control for the spacecraft formation flying are given in the section of the cooperative control for spacecraft formation flying. The section of the motion estimation of spacecraft based on the nonlinear filtering summarizes the results on the estimation of spacecraft attitude based on the improved volume Kalman filtering. The results on robust fault-tolerant control based on eigenstructure assignment and robust actuator fault diagnosis scheme for satellite attitude control systems are summarized in the section of the robust fault-tolerant control for spacecraft. The results on the global stabilization control for spacecraft orbital rendezvous system and the model reference output tracking control for spacecraft are prescribed in the section of robust orbital control for spacecraft. Finally， we summarize the related results on the robust attitude control of spacecraft. The report lists some semi-physical simulations to illustrate the effectiveness and practicability of the obtained results
