| 摘 要： | 开关磁阻电机（SRM）的双凸板结构导致其运行时磁链具有非线性特点,因而精确建立电机的数学模型比较困难.在分析开关磁阻电机的非线性特性和磁链曲线后,提出了利用一种指数函数来构建磁链曲线的新型数学模型.结合Ansoft软件的电磁分析功能,利用Matlab软件搭建一台3 kW、12/8极SRM的控制仿真模型,在角度位置控制（APC）模式下进行了仿真分析,并与实验结果进行了比较,验证了该磁链非线性模型的准确性.

| Abstract: | The flux linkage of switched reluctance motor （SRM） has serious nonlinear characteristic forits double salient pole structure, so it is difficult to build an exact mathematics model of SRM. Tosolve this problem, by studying deeply the nonlinear characteristic and flux linkage curves, the paperproposed a new mathematical model using an exponential function. Combining with the electromagnetic analysis function of Ansoft, a control simulation model of a 3 kW 12/8 poles switched reluctance motor was built by Matlab. The angularpositioncontrol （APC） mode was simulated. The accuracy ofthe new mathematical model was verified by comparing the simulation results with experimental results. |
