摘　　要：以8/6结构开关磁阻电动机调速系统为研究对象,分析了其转速闭环条件下磁阻电动机状态对H桥斩波开关的影响,并给出了磁阻电动机在2种不同的混沌态下时斩波开关电压功率谱的计算方法。结合开关磁阻电动机非线性仿真模型和特征值求概率密度分布的方法,利用复化辛普森公式计算2种情况下的系统斩波管电压功率谱,证明了混沌对降低系统电磁干扰的有效性。Matlab仿真和实验结果与理论分析结果一致,证实了混沌在提高电力传动系统电磁兼容性能方面具有良好的应用前景。The paper took speed regulation system of switched reluctance motor with 8/6 structure as object of study, analyzed influence of state of switched reluctance motor on H-bridge chopper switch under condition that rotate speed is closed loop, and gave calculation method of voltage power spectrum of chopper switch in two kinds of chaotic state. It proved effectiveness of suppression of electromagnetic interference by chaos with nonlinear simulation model of switched reluctance motor and method of getting probability density distribution by eigenvalue, and calculated voltage power spectrum of chopper switch under two conditions by composite Simpson formula. The simulation and experimental results approximately agree with theory analysis results, confirm that chaos has great potentiality in improving electromagnetic compatibility of power transmission system.
