Examples
- Study on pulsating stress of turbulence with strange attractor theory
用奇怪吸引子理论研究紊流脉动压力特性 - We reconstructed the phase space and calculated the nonlinear parameters such as correlation dimension , the largest lyapunov exponent , approximate entropy , and l - z complexity of the data . it can be conclud from the results that the reconstruction of heart beat rate signal is strange , its correlation dimension is between 5 to 7 and have the character of fractal dimension , its largest lyapunov exponent is larger than zero , its approximate entropy and l - z complexity are obviously differ from noise . we can draw a conclusion from all above : the heart beat rate signal is n ' t simple noise , it is high dimensional chaos obeys certain dynamical law
我们还对信号进行了相空间重构，计算了信号的关联维数、最大lyapunov指数、近似熵和复杂度这几个非线性特征量，我们发现，心率信号的吸引子是奇怪吸引子，关联维数介于5到7之间，具有分维的特征，其最大lyapunov指数大于0 ，其近似熵值和复杂度值明显区别于噪声，这说明心率信号不是随机噪声，它是服从确定性动力学规律的高维混沌信号。 - The results show that the chaotic motions of the bloch wall are suppressed successfully , that is , the new strategy is successful and effective . in a time - continuous dynamical system , a new optimal control scheme is proposed base on the krasovskii theory and is utilized to control the chaos in the newton - leipnik system which has double strange attractors . it is found that the n - l system can converge onto a selected fixed point rapidly and perfectly through asymptotic mode
在时间连续动力系统方面，基于krasovskii理论本文提出了一种的新优化控制方法，并利用这一方法对一类具有双奇怪吸引子的newton - leipnik ( n - l )系统进行了混沌抑制，结果表明一旦控制启动，系统行为能够迅速渐近稳定于目标平衡点。 - It is usually deleterious when there appears chaos in the systems owing to chaos uncertainty , therefore , it is necessary to control chaos if chaos exists ; on the other hand , chaos contains much information , but the trajectory of chaos attractor is almost unstable , rapidly variational and hard to hold on . the saved information is easy to alternate , so it is unuseful unless chaos is under controlled . chaos control has attracted a great deal of attention from non - linear and this problem is also a complex problem of nonlinear
通常情况下，由于混沌的不确定性，系统中出现混沌是有害的，有必要在系统出现混沌时进行控制；而另一方面，混沌包含着极其丰富的信息，但是混沌奇怪吸引子内的轨线(或信息)是高度不稳定的，瞬息万变，难以捕捉，因此即使混沌信息存储下来，也会改变，往往难以重复识别，如不加以控制，根本无法应用。
