李亚普诺夫指数 meaning in English
lyapunov index
Examples
- In addition , a theoretical model was also developed to predict the width of the two - fluid hydrodynamically - focused stream for a given volumetric flow rate ratio , dynamic viscosity ratio of the two - fluid , and microchannel aspect ratio
而粒子混沌行为强度可藉由李亚普诺夫指数量化，因而找出其最佳切换频率，此最佳切换频率也经由直接数值模拟方式被验证。 - After that , we drew the definitions of lyapunov exponent , lyapunov exponent spectrum and the largest lyapunov exponent . at last we studied the meaning of lyapunov exponent and the relationship between lyapunov exponent and eigenvalue of linear system
总结了判断系统是否是混沌系统的几种方法，对连续混沌动力学系统进行特性分析，研究了李亚普诺夫指数的意义以及与系统特征值的关系。 - In addition the h . kantz method is applied to analyze the time series of the motor current , the maximal lyapunov exponent calculation is realized , the criterion for the motor chaos is brought forward , the existence of chaotic phenomenon in the induction motor is verified by the characteristic exponents , which proves theoretically that the chaotic movement is one of the reasons that results in the low frequency oscillation of the induction motor system
应用h . kantz方法对电机电流信号的时间序列分析，实现了最大李亚普诺夫指数的具体算法，提出了电机出现混沌运动的判定根据，通过特征指数验证了异步电动机现象的存在，从理论上说明混沌运动是异步电动机系统产生低频振荡的原因之一。第三部分深入研究了系统低频振荡的主要影响因素。
