摘要
在有限元分析的静态特性参数基础上,建立了开关磁阻电机(SRM)的一个新的快速解析非线性模型,模型的磁链曲线和转矩曲线与有限元的分析结果都比较吻合。基于Dymola平台建立了SRM及其驱动系统的模块化模型,目的是建立一个通用性强、扩展性好,并相对完善的SRM元件库,进而搭建系统模型,分析其动态性能参数以达到优化设计。本课题所开发的SRM模型库也适用于基于Dymola平台所开发的其他动力系统(如航空动力系统)的耦合仿真分析,为综合系统的优化设计提供分析依据。基于Dymola/Modelica给出仿真实例,验证了模型的准确性和可行性。
Based on the static characteristic data from FEM, a new analytical nonlinear model of SRM for rapid calculation is presented . It matches the curves of both flux linkage and electromagnetic torque derived from FEM. The SRM drive （SRD） model is then modularly developed on Dymola. The purpose is to build a generic, expandable, and rather complete SRD model library for its dynamic simulation and analysis, and for the system-level simula- tion analysis when it＇ s coupled with other power system like aircraft engine. It＇ s expected to alleviate the design and optimization of the whole system. An Dymola/Modelica-based example of SRD is exhibited at the end for the validation of the model.
