Trajectory planning and control for space rendezvous with non-cooperative targets in line-of-sight coordinate system
摘要
Abstract
To address the multi-constraint autonomous rendezvous problem for maneuvering non-cooperative space targets,this paper proposes a trajectory planning and control method in the Line-of-Sight(LOS)coordinate frame of the chaser spacecraft,which integrates a genetic algorithm with Linear Time-Varying Model Predictive Control(LTV-MPC).The proposed method overcomes the limitations of conventional controllers designed in the Local Vertical Local Horizontal(LVLH)frame for rendezvous missions with maneuvering non-cooperative targets,while avoiding naviga-tion coordinate transformation errors.First,a relative motion dynamic model between the non-cooperative target and the chaser spacecraft is established in the chaser's LOS coordinate frame.Then,taking full account of multiple con-straints including dynamics,control saturation and safety constraints,an optimization model is constructed with a fuel-optimal performance index.The model is solved using a genetic algorithm,taking advantage of its global convergence and strong constraint-handling ability,to obtain the optimal nominal trajectory.Finally,benefiting from its advantages in conveniently handling multiple constraints and uncertainties,an LTV-MPC-based closed-loop tracking controller is designed to track the aforementioned nominal trajectory.Numerical simulations show that the designed trajectory satis-fies complex engineering constraints including control,dynamics and safety,and is fuel-optimal,controllable and achievable.In addition,the controller exhibits favorable control accuracy and robustness in the presence of uncertain-ties,providing an effective solution to the rendezvous problem with maneuvering non-cooperative space targets.关键词
