摘　　要：开关磁阻电动机(Switch Reluctance Motor,SRM)由于铁芯磁通的高饱和、绕组磁链的非线性,致使其组成的开关磁阻电动机调速系统(Switch Reluctance Drive,SRD)建模困难。针对该问题,提出了一种运用Ansoft Maxwell2D和Matlab/Simulink建立SRD调速系统非线性模型的方法。首先,在给定的SRM结构尺寸下,利用Ansoft Maxwell 2D得到静态场下SRD的磁链、电磁转矩数据,并将其导入Matlab,在Simulink里建立SRD的非线性模型。其次,在既定控制策略下,建立了SRD调速系统的仿真模型。仿真结果表明该建模方法的合理性和有效性,为分析和设计SRD调速系统提供了一种新方法。The high saturation of the core flux and the nonlinearity of the winding flux of the switch reluctance motor(SRM)makes difficult to model the switched reluctance motor drive(SRD). To solve this problem,this paper puts forward a method of establishing an SRD nonlinear model by Ansoft Maxwell 2D and Matlab/Simulink. At first,under the given structure size of SRM,the flux linkage and electromagnetic torque data of switched reluctance motor in the static field are obtained by Ansoft Maxwell 2D,then imported into Matlab,and a nonlinear model of switched SRM is established in Simulink. Secondly,under the given control strategy,a simulation model of SRD is established. The simulation results show that the modeling method is reasonable and effective,which provides a new method for the analysis and design of switched reluctance motor speed control system.
