摘要
针对平流层飞艇能源系统,建立能反映该系统特性的小信号模型,特别是加入了推进用直流无刷电机,该模型能够描述能源系统各部分之间的输入输出关系和电源控制器的输出动态特性。另外,基于小信号模型和相应的线性化仿真结果,采用特征值法分析太阳辐照度、太阳电池工作温度、电源控制系统参数、电机转矩系数和电机控制系统参数等一些关键参数对能源系统小干扰稳定性的影响。该小信号模型的建立和分析结果为平流层飞艇能源系统的参数优化设计和稳定性分析提供了重要的参考依据。
In this paper,a small signal model of stratospheric airship energy system that can reflect its characteristics is established,especially the addition of a brushless DC motor for propulsion.This model can describe the input-output relationship between the various parts of the energy system and the dynamic characteristics of the power controller.In addition,based on the small signal model and its linearization results,the eigenvalue method is used to analyze the influence of some key parameters on the small signal stability of the system,these parameters include irradiance,solar cell operating temperature,power control system parameters,motor torque coefficient and motor control system parameters.This model and analysis results provides an important reference for the parameter optimization design and stability analysis of stratospheric airship energy system.
