开关磁阻电机的非线性解析模型及其在航空系统仿真中的应用

提出了开关磁阻电机的一个改进的快速非线性解析模型.该模型较好地兼顾了精确度及可快速计算性,并基于新一代的综合系统建模仿真工具——Dymola/Modelica对开关磁阻电机驱动系统建立模块化元件模型库.该模型库是作为航空动力系统元件模型库的一个子库,其建立充分利用了Modelica的非因果性特点,更好地解决了子系统耦合的问题,因此可重用性更强.最后给出了开关磁阻电机及其和航空发动机耦合的仿真实例,验证了模型的准确性以及本思路的可行性.

An Analytical Nonlinear Model of SRM and Its Application in the System-Level Simulation of Aircraft Power System

An analytical nonlinear model of switched reluctance machine(SRM) for rapid calculation was presented.It proves to be satisfactory in both accuracy and calculation speed.The model of SRM drive(SRD) was then modularly developed as a package based on Dymola/Modelica,a new-generation modeling and simulation tool which is especially suitable for complex multi-disciplinary system.The SRD model package is built as a sub-library of an aircraft power system model library.The non-causality of Modelica better solves coupling problems among different sub-system models.Therefore,the package is better reusable.Examples of both SRD alone and its coupling with aircraft engine were exhibited to verify the validity of the model and the ideas.
