摘要
Abstract
As rendezvous and approach perations frequently appear in various space missions related to the development of aerospace technology,improving the rapid orbit insertion and mission expansion of in-orbit spacecraft is of great significance for saving manpower and material resources.A rapid optimization framework for spacecraft trajectory based on convex optimization techniques was proposed by Birkhoff pseudospectral method.A dynamic model of two-body relative motion was established,optimal control theory was introduced,and convex optimization techniques were used to handle nonlinear constraints.The theoretical frameworks of Birkhoff pseudospectral method based on first-order differentiation(FBPSM)and second-order differentiation(SBPSM)were developed.The results indicate that FBPSM and SBPSM not only inherit the solving advantages of traditional pseudospectral methods,but also increase computational efficiency by about three times in terms of complex dynamical systems.This study provides the theoretical reference and technical support for real-time reconstruction and rapid optimization of spacecraft trajectories.关键词
