【摘要】 基于Matlab/Simulink,利用动态和静态电感等磁参数建立了一种开关磁阻电机的非线性磁参数模型。在电机磁场二维有限元数值计算的基础上,采用增强型能量增量法,计算得到电机的动态电感和静态电感;然后通过三次样条插值求取静态电感关于位置角的导数;再利用Matlab/Simulink中的查表模块建立开关磁阻电机的非线性模型。该模型中避免了微分环节,提高了仿真速度;可实时分析感应电动势和运动电动势。更多还原

【Abstract】 This paper presented a nonlinear magnetization data model of switched reluctance motor(SRM)using dynamic inductance and static inductance based on Matlab/Smulink.The dynamic inductance and static inductance of SRM were calculated with an enhanced incremental energy method after the 2D finite element analysis of magnetic field.Then the derivative of static inductance with rotor position angle was computed by cubic spline interpolating function.Finally established the nonlinear model of SRM was with the lookup table in Matlab/Simulink.The model avoided the differential computation,the simulation speed was improved obviously,and the induced electromotive force and motion electromotive force can be studied real-timely.更多还原
