摘　　要：为了实现人机耦合振荡的在线探测,提出了适于实时计算的滑动窗口Fourier变换递推算法和与人机耦合振荡相关的飞机操纵振荡特征,并通过人机耦合振荡试飞数据的计算,分析了操纵振荡特征的合理、有效性。最后指出拟进一步开展的研究工作及建议。This paper presents the real-time algorithm of recursive Fourier transform for preprocessing aircraft control/response signals and extracting methodology of aircraft control oscillation characteristic for fuzzy APC/PIO online detection. Through extracting from flight test data of the aircraft pilot coupling, the control oscillation characteristic parameters were analyzed to be reasonable and effectiveness. Finally, some suggestions were put forward to further research.
