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。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 operationa/ 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.
