含无质量系绳的卫星系统平面运动和常规动力学

研究绳系卫星系统在同一轨道平面内运动，由子星－母星之间相对位置向量描述，亦即由该向量的长度变化和方位角的化而决定，在引入距离速率控制算法之后，系统的动力学主要由方位角运动而定，当母星轨道为圆形时，系统运动状态具有极限点，而在椭圆轨道下则有极限环，采用了非线性动态系统的方法和技术来计算极限状态和分析它们的稳定特性，用本文中方法对TSS－1以及其他绳系卫星系统方案作了数值模拟。

IN-PLANAR MOTION AND REGULAR DYNAMICS OF MASS-LESS TETHER SATELLITE SYSTEM

The motion of tether satellite system inner the orbital plane is described by the relative position vector between the subsatellite and base-satellite. As soon as the range rate control algorithm is established, the motion of the system is determined by the direction angle of the position vector, which has a stationary state. The stationary state is a limit point if the orbit is circular, and a limit cycle if the orbit is elliptical. An iterative algorithm is introduced to compute the limit cycle, and a method for stability analysis of the stationary state is also discussed. Computer simulations are carried out for both the limit point and limit cycle.
