摘要

摘要: 为保证在轨卫星运行安全，对于碰撞概率较高的空间交会情况需要进行规避机动，防止在轨卫星与空间碎片碰撞.选取连续推力策略进行规避机动，将空间碰撞规避过程转化为满足复杂约束的最优控制问题，采用高斯伪谱法对最优控制律进行求解，求解结果满足相应约束.研究结果为航天器有效规避空间碰撞威胁提供了有力支持.

Abstract: In order to ensure the safety of active satellite, it is necessary to perform an orbit maneuver before the collision between space debris and satellite to protect satellite from space debris. The strategy of continuous-thrust is chosen for avoiding collision. The collision avoidance process is converted to optimal control problem with complicated constraints, while Gauss pseudospectral method is used to solve this problem and the result meets the requirements of avoidance. The simulation results show that the new method can decrease the consumption of fuel. It is significant for avoiding collision between space debris and the satellite.
