Abstract: Due to the troubles in studying and designing fractional-order chaotic systems at present，a dynamic simulation method for fractional-order chaotic systems based on Simulink is proposed.Taking the fractional-order Jerk system as an example，a simulation model for fractional-order chaotic system is built based on fractional-order system equation.The variable law of system variables can be observed dynamically.The simulation results show that a dynamic simulation method for fractional-order chaotic systems based on Simulink is feasible.In addition，the designing method of hardware for fractional-order chaotic system is given. The digital realization of the fractional-order chaotic system has been provided a new way.

摘要： 由于目前分数阶混沌的理论分析和硬件设计都比较烦琐，提出了分数阶混沌系统的Simulink动态仿真方法。以分数阶Jerk系统为例，根据分数阶系统方程搭建分数阶混沌系统仿真模型，可动态地观察系统变量的变化规律。仿真结果表明，分数阶混沌系统的Simulink动态仿真方法是一种切实可行的分析方法。此外，还给出了分数阶混沌系统直接进行硬件设计的方法，这为分数阶混沌系统的数字设计提供了新的思路。
