基于多脉冲凸规划的避碰机动Optimization

Collision Avoidance Maneuver Optimization with a Multiple-Impulse Convex Formulation

Roberto Armellin

摘要:

提出了一种计算短期相遇最优避碰机动的方法。机动被建模为多脉冲处理脉冲的情况下,并近似有限燃烧弧与短的警报时间或使用低推力推进。机动设计被表述为一系列凸优化问题,通过最先进的原始-对偶邻域点算法在多项式时间内求解。所提出的方法计算最优解没有假设的推力弧结构和推力方向。对于具有数百个变量和约束的最优化问题,执行时间仅为几分之一秒,因此适合于自主计算。

英文摘要:

A method to compute optimal collision avoidance maneuvers for short-term encounters is presented. The maneuvers are modeled as multiple-impulses to handle impulsive cases and to approximate finite burn arcs associated either with short alert times or the use of low-thrust propulsion. The maneuver design is formulated as a sequence of convex optimization problems solved in polynomial time by state-of-the-art primal-dual interior-point algorithms. The proposed approach calculates optimal solutions without assumptions about the thrust arc structure and thrust direction. The execution time is fraction of a second for an optimization problem with hundreds of variables and constraints, making it suitable for autonomous calculations.
