航空直流起动发电机起动过程分析

Analysis of Starting Process of Aero Starter-generator

航空直流起动发电机驱动飞机发动机起动要经历多次换路,分析了每次换路的物理过程,建立了起动过程的动态模型和状态方程。利用该数学模型计算了航空直流起动发电机的起动过程,所计算的物理量包括电流、转速、转矩等。按计算结果画出了动态曲线,使用软件MATLAB编程实现计算。

The starting process of the aero starter-generator will undergo many phases of exchanged circuit states.The physical process of each exchanged state is analyzed in the paper.The dynamic models and state equations of the stating process are established.The staring process of a starter-generator are calculated by the mathematics models,the calculated physical quantity include the current ,rotational speed and torque.The diagrams are done by software MATLAB.
