The invention discloses a spacecraft approaching maneuver tracking control method based on observation and collision avoidance constraints, and the method comprises the steps: employing dual quaternion description to establish a relative kinematics and dynamics model, employing a relative pose dual quaternion to construct an observation sight line constraint and a collision avoidance safety constraint, designing an artificial potential function based on the two constraints, and carrying out the calculation of the artificial potential function. A near maneuver tracking control law is further designed, and the provided near maneuver tracking control method can enable the service spacecraft to approach the target spacecraft under the condition that observation and safety constraints are met all the time and finally keep stable tracking of the target spacecraft.

    本发明公开了一种观测和避碰约束的航天器临近机动跟踪控制方法,包括采用对偶四元数描述建立了相对运动学和动力学模型,利用相对位姿对偶四元数构建了观测视线约束和避碰安全约束,基于两种约束设计了人工势函数,并进一步设计了临近机动跟踪控制律,所提的临近机动跟踪控制方法可以使服务航天器在始终满足观测和安全约束下抵近目标航天器,并最终保持对其稳定跟踪。
