论文摘要
本论文中提出的工作的主要重点是制定基于最佳控制的形成控制策略，以实现具有限制计算和存储容量的小型卫星的高精度形成。使用最近开发的模型预测性静态编程（MPSP）和广义MPSP算法，为小卫星的形成飞行提供了次优引导逻辑。拟议的指导方案对于高偏心的主要卫星轨道以及首席卫星和副卫星之间的较大分离距离都是有效的。使用标准线性二次调节器（LQR）解决方案（用作MPSP的猜测解决方案）和另一个非线性控制器，有限的状态依赖性Ricatti方程（SDRE）的比较研究表明，MPSP指导可以以更高的准确性和更少的控制用法来实现目标，以更高的准确性和较少的控制用法来实现目标。
The main focus of the work presented in this thesis is to develop an optimal control based formation flying control strategy for high precision formation flying of small satellites that have restricted computation and storage capacity. Using the recently developed model predictive static programming (MPSP), and Generalized MPSP algorithm a suboptimal guidance logic is presented for the formation flying of small satellites. The proposed guidance scheme is valid both for high eccentricity chief satellite orbits as well as the large separation distance between the chief and deputy satellites. Comparative study with standard Linear Quadratic Regulator (LQR) solution (which serves as a guess solution for MPSP) and another nonlinear controller, Finite-time State-Dependent Ricatti Equation (SDRE) reveals that MPSP guidance achieves the objective with higher accuracy and with a lesser amount of control usage.
