摘　　要：针对无刷直流电机开环系统等效非线性数学模型,运用混沌分析的方法对其存在的混沌现象进行了理论分析和仿真实验,确定了混沌系统的对称性、平衡点稳定性等相关理论问题,揭示了无刷直流电机系统通往混沌之路,并设计出与混沌数学模型相应的模拟电子电路,由虚拟示波器显示对应的电路运行状态图验证了该理论研究,进一步为无刷直流电机的混沌分析和抑制提出了新思路。Aiming at the equal effective non-linear mathematical model in the brushless DC motor open-loop system,this paper analyzed the existing chaotic phenomenon theoretically with the chaotic analysis method and carried out simulation experiments,confirming symmetry of chaotic system and balance point stability etc related theory problems and opening out that the brushless DC motor system was on the road from stability to instability.The analog electronic circuit corresponding to chaotic mathematical model was designed.Theoretical study was verified by virtual oscillograph displaying the corresponding circuit operation state graph,which provides new thinking way for chaotic analysis and restriction of the brushless DC motor further.
