自由飞行空间机器人高性能轨迹跟踪控制
High-performance Trajectory Tracking Control for Free-flying Space Robots
摘要
Abstract
Taking free-flying space robots as the research object,an improved super-twisting sliding mode control strategy with a finite-time disturbance observer is proposed to meet the high-performance trajectory tracking control requirements of space robots.Based on the dynamic equations of the space ro-bot,a finite-time observer is employed to estimate and compensate for system parameter uncertainties and external disturbances.To enhance system robustness,reduce chattering,and accelerate convergence,a traj-ectory tracking controller based on super-twisting sliding mode is designed for the space robot.Compara-tive simulation results demonstrate that the proposed control strategy provides excellent trajectory track-ing performance and robustness for the space robot.关键词
