摘要 通过数值计算、理论推导分析了一个三维类Lorenz混沌系统的基本动力学特性,并通过数值仿真、相图、Poincare截面图和功率谱研究了这个系统的混沌行为.然后,构建一个受控系统并利用Lyapunov指数谱、分叉图分析了该系统混沌吸引子的形成机制,通过对控制参数的改变,系统的混沌运动可以得到有效控制。 Some basic dynamical properties of a three-dimensional Lorenz-like chaotic system are analyzed by means of numerical value calculation and theoretical deducing. The chaotic behaviors of the chaotic system is studied via nu- merical simulation, phase diagram, Poincare mapping and power spectrum. A controller of the Lorenz-like system is then constructed to study the forming mechanism of the chaotic attractor by Lyapunov exponent and bifurcation diagram. The chaotic movement of the Lorenz-like system can be well controlled by adjusting the control parameters.
