| 摘 要： | 为了对飞机-驾驶员耦合(APC)或驾驶员诱发振荡(PIO)现象实现在线探测,提出了适于实时计算的滑动窗口傅立叶变换递推算法、相关特征的模糊隶属函数以及基于模糊逻辑的识别模型。各种情况飞行试验数据的计算和分析表明,该方法对探测APC/PIO是有效、可行的。最后提出了进一步研究的若干建议。

| Abstract: | To realize online detection of aircraft pilot coupling(APC) or pilot induced oscillation(PIO),this paper presents a recursive algorithm of Fourier transform with a sliding window,the membership functions for relevant features,and the identifying model based on fuzzy logic.Through calculating and analyzing for the varieties of flight test data,it is shown that this method is valid and feasible for detecting the APC/PIO.Finally,some suggestions were put forward to further research. |
