摘要

卫星被认为是相对于标称椭圆轨道运动的，其动力学通常由Tschaunner-Hepel方程（T-H方程）描述。在本文中，我们提出将由具有二阶矩阵形式的线性T-H方程表示的二阶时变系统转换为一阶时变。然后，用矩阵序列方法研究了一阶时变系统的可控性，其中e＝0。同时，我们研究了具有特定测量形式的一阶时变系统的可观测性。分别通过算例验证了矩阵序列法在可控性和可观测性分析中的优势。对偶理论用于研究T-H方程的对偶系统的能控性和可观测性。得出了相应的结论。

Controllability Analysis of Linear Time-Varying T-H Equation with Matrix Sequence Method

A satellite is considered to be moving relative to a nominal elliptical orbit, whose dynamics are usually described by the Tschaunner-Hempel equation (T-H equation). In this paper, we propose to transform the second-order time-varying system represented by the linear T-H equation with a second-order matrix form into a first-order time-varying system. Then, the controllability of the first-order time-varying system is investigated with the matrix sequence method including e = 0 . Meanwhile, we study the observability of the first-order time-varying system with a specific form of measurement. The advantages of the matrix sequence method for controllability and observability analysis are tested by numerical examples, respectively. Dual theory is used to investigate the controllability and observability of the corresponding dual system of the T-H equation. The corresponding conclusions are obtained.
