【摘要】 本文从可达性分析的角度考虑一对卫星的编队飞行控制问题,采用凸多面体描述控制对象的可达集,并根据可达集给出编队飞行中受控卫星的控制量。凸多面体描述可达集的缺点是当状态变量维数较高时,计算复杂度非常高,难以满足控制的实时性要求,因此本文采用一种近似复杂多面体的方法来简化可达集计算。计算和仿真结果表明,采用近似多面体可有效降低运算的复杂性,并且可根据计算可达集得到的控制量来控制一对卫星的编队飞行。更多还原

【Abstract】 In this paper,the problem of formation flying control of a pair of satellites based on reachability analysis is considered.A convex polyhedron is used to describe the reachable set of the control object,and the control input of the controlled satellites is given according to the reachable set.The drawback of describing reachable sets by polyhedra is that when the dimension of state is high,it will result in high computational complexity and will be difficult to meet the requirements of real-time control.Therefore,an approximate approach of complex polyhedra is used to compute the reachable set.The results of calculation and simulation show that the approximate polyhedra can effectively reduce the complexity of the computation.And the formation flying of a pair of satellites can be controlled effectively according to the reachable sets.更多还原
