摘要
提出了一套识别飞机系统动态特性的方法。对于短时激励信号,可同时采取时域法和频域法;对长时激励信号仅采取频域法。方法验证采用了变稳飞机电传系统试飞数据和专门的仿真试验数据。结果表明:该方法可解决电传飞机系统识别和评定中的许多问题,并为更进一步的应用研究打下基础。
The methods, available to both short and long time stimulation input signals, are presented for identifying the system dynamic characteristic of the Fly—By—Wire aircraft respectively in time and/or frequency domain. They are verified by using the data from the BW—1 variable stability aircraft flight test and the specific simulation test. The results shows it correct and practicable to adopt the methods to solve the problems met in identifying and valuating the fly—by—wire aircraft system qualities. Finally, no doubt, the solid foundation has been established for further application research.
