摘要

In orderto research the control system of switched reluctance motor(SRM)for vehicle,take the 4-phases 8/6 poles SRM for instance,building up the dynamic differential equation(including circuit equation,mechanical equation,Mechanical & Electronic related equation)of SRM based on its operational principle.In addition,setting up the nonlinear mathematical model of SRM which is espressed by state equation.In theory,the nonlinear model describes the dynamic properties and the relationship among electricity,magnetism and mechanics of SRM accurately and intactly.The building of nonlinear model lays the theoretical groundwork for the research on control method of switched reluctance motor drivers.%为研究车用开关磁阻电机(SRM)的控制系统,以四相8/6极结构开关磁阻电机为例,依据其工作原理建立了SRM的动态过程微分方程(包括电路方程、机械方程和机电联系方程),并以动态微分方程为基础建立了SRM的用状态方程表示的非线性数学模型,此非线性模型从理论上比较准确、完整地描述了SRM的电磁力关系和动态性能.此模型的建立可为车用开关磁阻电机系统控制方法的研究奠定理论基础.
