摘要
研究了外力矩作用下刚体转动动力学系统存在的混沌吸引子类型、数量和特性,分析了5个平衡点的属性。系统状态在5个平衡点邻域沿某方向的收敛和沿某方向的发散,可以形成各种各样的周期吸引子,单核、双核、三核、连体四核、单体四核混沌吸引子。该系统中包含的各类混沌运动形式复杂,吸引子种类繁多。
The quantity and characteristic of chaotic and the attribute of five equilibria is analyzed. The attractors in rigid-body attitude dynamical system is researched state trajectory of system near each equilibria is constringency along some direction, or is emanative along another direction. These state trajectories come into being periodic at- tractors or chaotic attractors with single-core, or two-core, or three-core, or fore-core. There are innumerable chaotic attractors in this system.
