利用非线性磁化曲线簇，结合外部电路方程和有限元(FEM)仿真，在Matlab/Simulink中通过实时的电感插值法建立开关磁阻电机非线性模型。并以此模型为基础，对开关磁阻电机驱动系统进行高低速仿真研究，结果验证此电机模型及其驱动系统的有效性。同时给出开通角-5°～-3°，关断角-25°~-30°之间的相电流波形，平均转矩随开关角变化曲线。在转速为3450 r/min时最高效率和最大平均转矩条件下的最优开通角为-1°，关断角为22°。开关磁阻电机角度位置运行控制下开通角和关断角的不同组合，可以提高电机效率，降低噪声，抑制振动，为开关磁阻电机优化指明方向。%Taking advantage of nonlinear magnetization curve clusters and combined with the ex-ternal circuit equation and finite element method (FEM) simulation, a switched reluctance motor nonlin-ear model is established in the Matlab/Simulink by the inductance of the real-time interpolation method. Based on this model, study the high speed and low speed for switch reluctance motor drive system, the results demonstrate the effectiveness of the motor model and its drive system. At the same time, take the phase current waveform opening angle between -5° to -3°, the turn-off angle between -25° to 30° and the average torque curve with the change of switch angle. When we take the rotating speed of 3450 r/min under the condition of maximum efficiency and maximum average torque, we can acquire that the optimal opening angle is -1° and optimal turn-off angle is 22°.The different combination of opening angles and turn-off angles, for switched reluctance motor running angle position control, can significantly improve the efficiency of the motor, reduce noise and suppress the vibration, provide the direction for switched reluctance motor optimization.
