为解决开关磁阻电机的转矩脉动大、电磁干扰严重，本文介绍了一种基于蔡氏电路的混沌扩频方法，通过Matlab编写蔡氏电路函数和蔡氏混沌随机PWM信号，并和常规PWM信号比较，分析两种PWM驱动脉冲调制下的母线电流谐波的频谱分布。最后将MATLAB/SIMULINK软件中的仿真与dsPACE实验平台连接观察并分析常规PWM与混沌PWM控制下的开关磁阻电机调速系统电磁干扰。

In order to solve switched reluctance motor torque ripple and serious electromagnetic interference, this paper introduces a kind of chaotic spread spectrum method based on chuas circuits. Through the Matlab writing chuas circuits function and chuas chaotic random PWM signal, and comparing with conventional PWM, it analyzes the bus current harmonic spectrum of two kinds of PWM drive pulse modulation. The simulation in MATLAB/SIMULINK software connects tohe dsPACE to observe, and analyzes electromagnetic interference of switched reluctance drive under the control of the conventional PWM and Chaotic PWM.
