摘要
针对飞机动力系统的性能检测还是传统的人工检测手段,以工程应用需求及其提供的试验数据为依据,结合Sa-ber仿真软件的特点,利用基于实验数据、基于原理图等建模方法,并依据不同的建模方法建立了由电气负载模型与控制模型组成的飞机动力系统混合信号模型。通过实验验证了整个系统模型,实验结果表明了该系统模型的准确性、有效性和实用性。仿真结果与试验对比,仿真结果较真实地反映了动力系统相关参数的动态变化过程,仿真系统的收敛性强,为大系统的仿真应用提供了有益参考。
According to the traditional manual examination method of aircraft power system＇ s performance, based on engineering application requirements and relevant data, and combing features of saber, simulation methods based on experimental data and schematic diagram is used. Aircraft power＇ s the electrical load model and the control model are established. The simulation result and the experimental is contrast, system related parameter＇ s dynamic change process is simulation result reflected. The model accuracy, the validity and the usability is experimental result proved. And beneficial reference for the large-scale system simulation application is provided.
