摘要
以航天器姿态运动为工程背景,以三轴气浮台为物理实验平台,研究了混沌控制与反控制问题;提出了用外控制力矩进行混沌化,然后再将混沌控制信号施加于动量轮来进行混沌控制实验的方法;通过引入非线性解耦反馈,构造了一种易于物理实现的具有更强代表性的连续非线性系统,从中发现了一大类新的形态各异的混沌吸引子。
Taking attitude motion of spacecraft as engineering background for exploring chaos, and 3-axis air bearing table as experimental equipment, a series of investigation on control and anti-control for chaos was carried on. An experiment method for control of chaos was developed. The method was that the system was chaotifyed by external control torques and controlled by momentmn wheels. A more representative continuous nonlinear system, which was realizable easily, was educed with introducing decoupled nonlinear feedback. A new class of chaotic attractors was found in this system.
