摘要
Lyapunov指数是衡量系统动力学特性的重要指标。本文针对切换系统,综述了目前常用Lyapunov指数的三种计算方法:庞加莱映射法、时间序列法和混沌同步法。通过分析和比较其特点及优缺点,详细探讨各方法在切换系统中的应用。
Lyapunov exponent is important for analyzing nonlinear dynamics. Firstly, this paper reviewed the current commonly used three methods to calculate Lyapunov exponents for switching system, which are Poincaré mapping method, Time series method and Chaos synchronization method. Finally, we discuss the application in the switching system by analyzing and comparing the advantages and disadvantages of each method.
