文章提出了一种基于行为的太阳帆群编队路径规划方法。通过行为控制技术,在有限的感知信息条件下,便可获得自动的分布式控制律,将同质的各太阳帆导引至目标构型。导引过程中,各帆期望速度均为所设置三个行为速度(聚集、排斥、驻留)的矢量和,而各行为参数则利用目标构型的对称性进行设置。特别地,为了降低控制成本,聚集行为在仿真中利用了太阳引力、光压实际环境下形成的太阳帆轨道性质进行改造。通过日心悬浮轨道上的太阳帆群编队数值仿真,验证了文中方法的有效性和优越性。仿真结果表明,仅通过设置三个简单的行为,便可在日心悬浮轨道上得到许多有价值的太阳帆群构型。此外,通过修改其中的聚集行为,该方法可以很容易地移植到太阳帆行星悬浮轨道以及椭圆型三体问题中的太阳帆轨道编队应用上来。
This paper presents a behavioral method of solar sail group formation routing. Through behavioral control technology, under the condition of limited perceptual information, an automatic distributed control law can be obtained to guide the homogeneous solar sail to the target configuration. During the guidance process, the expected velocities of the sails are all vector sum of the three set behaviors velocities (agglomeration, exclusion, residency), and the behavior parameters are set according to the symmetry of the target configuration. In particular, in order to reduce the control cost, the aggregation behavior uses the solar attraction force in the simulation to modify the solar sail orbit formed under the actual environment. The numerical simulation of the solar sail group formation on the hovering orbit of a heliocentric heart proves the effectiveness and superiority of the proposed method. Simulation results show that only by setting three simple behaviors, many valuable configurations of solar sails can be obtained on the heliocentric orbit. In addition, by modifying the aggregation behavior, the method can be easily applied to solar sail orbit formation applications in the solar sail orbit and the elliptic three-body problem.
