摘要：针对永磁同步电机的无量纲数学模型，数字仿真分析了该模型的动态特性。为了验证该无量纲系统的混沌现象，提出采用运算放大器、电阻和电容等元器件实现反相比例环节、反相加法环节和积分环节，从电路角度实现了该混沌系统。通过OrCAD/PSpice软件对该电路进行了仿真实验，观察参数的变化使系统从稳定状态变化到混沌状态的过程，实验结果与数字仿真是一致的。

Abstract: Based on the dimensionless mathematical model of a permanent magnet synchronous motor(PMSM), the dynamic behavior of the model was analyzed by digital simulation. To validate chaotic phenomenon of the system, a novel circuit consisting of inverse proportional component, inverse adder and integral component was proposed in the paper. It was realized by using circuit elements such as operational amplifiers, resistors and capacitors. The simulation was carried out by using OrCAD/PSpice. It can be seen that the behavior of the system can change from stability to chaos with the variation of parameters. The experimental results are consistent of the digital simulation.
