摘要
分析航天发电机交流瞬态电压产生的过程原因,根据交流无刷发电机原理结构图和相关的数学模型的基础上,用MATLAB/Simulink环境下进行发电机的仿真,得到的瞬态电压信号。根据GJB 181-2003《飞机供电特性》的相关要求,确定航空发电机交流模式下的电压瞬变和频率瞬变等瞬变参数,利用MATLAB进行编程,对采集到的信号进行分析处理,并在进一步对信号采用零相位滤波来减少输出的延时,最后得到相应的交流电压和交流频率的信号,对比其包络线,以判断是否符合相关要求。
Analysis the reasons for transient voltage of aviation generator,Based on the AC brushless generator principle,the structure diagram and the related mathematical model,the transient voltage signal is obtained by simulation of generator under MATLAB/Simulink environment.According to the relevant requirements of ＂GJB 181-2003＂ aircraft power supply characteristics,The transient parameters such as voltage transients and frequency transients under the AC mode of an aircraft generator are determined,and the signals are analyzed and processed by using MATLAB,and to reduce the output delay further by zero phase filter of wave signal,and finally get the corresponding signal the AC voltage and frequency,compared to its envelope,to determine whether to comply with the relevant requirements.
