提出了一种基于约束力思想的鲁棒的编队卫星构形精确保持的非线性控制方法.该方法首先将非线性和摄动条件下编队卫星构形保持问题转换为带有完整约束的拉格朗日动力学系统,然后将问题转换为一组微分代数方程,通过求解微分代数方程,确定编队卫星构形保持的非线性控制律.针对微分代数方程传统求解方法对误差敏感,相应的约束力控制法鲁棒性差的缺点,提出了编队卫星构形约束违约修正的方法,通过适当地选择违约修正因子,有效地抑制了编队卫星初始化、参考卫星轨道确定、相对动力学建模等误差的影响,提高了约束力控制法的鲁棒性。
A robust nonlinear control method based on the idea of constraint for the formation of a robust formation satellite formation is proposed. This method first transforms the formation configuration of formation satellites under non-linear and perturbed conditions into a Lagrangian Then the problem is transformed into a set of differential algebraic equations.The nonlinear algebraic laws of formation satellite formation are determined by solving the differential algebraic equations.For the traditional algebraic method of differential algebraic equations is sensitive to errors and the corresponding binding force This paper proposes a method to modify the default constraint of formation satellite formation constraint by properly choosing the default correction factor, which can effectively restrain the errors such as initialization of formation satellite, reference satellite orbit determination, relative dynamic modeling and other errors , Which improves the robustness of Binding Control Law.
