J2项摄动条件下空间非合作目标仅测角相对导航与交会博弈控制理论

Autonomous rendezvous is the necessary process to conduct on-orbit operation and servicing to the space non-cooperative target. In order to achieve the autonomous rendezvous between the chaser and target, angles-only relative navigation and rendezvous game control theories using positive optical camera under J2 perturbation will be studied in this project. Firstly, in the Cartesian coordinate centered on the mass-of-chaser, a J2 perturbed relative motion dynamics and its state transition matrix will be modeled. Secondly, a multi-constraint robust adaptive closed-loop guidance strategy integrated with angles-only relative navigation algorithm for mid-and-far range rendezvous phase will be proposed with considering the constraints of rendezvous windows, process/ terminal and fuel cost, and introducing of index of state observability and covariance. Lastly, as to solve the pursuit-evasion game between the chaser and target for proximity phase, a target-maneuver-immune line-of-sight control algorithm integrated with angels-only relative navigation will be studied while differential game theory is introduced to model the optimal control for pursuit-evasion problem and the coupled relationship between angles-only navigation and orbit control is utilized. The proposed research will present several novel theories and algorithm for space non-cooperative target angles-only rendezvous and it will provide theoretical foundation for the engineering application of the on-orbit operation and servicing.
