| 摘 要： | 驾驶员诱发振荡（PIO）是一类驾驶员不希望出现的人机耦合(APC)现象。探测器可根据飞机飞行数据识别是否有PIO发生。设计模糊逻辑探测器模型用于PIO探测关键在于模糊变量的选取与模糊推理的设计，模糊变量是由若干隶属函数描述的。根据对发生PIO时驾驶员的操纵与飞机运动特点的分析与总结，以及选取的特征参数的变化范围，对模型中的隶属函数进行设计，并对隶属函数的适应性和对识别结果的影响进行了分析。PIO数据的识别结果表明通过这种设计方法得到的模型可以用于PIO探测。

| Abstract: | Pilot induced oscillation (PIO) is a kind of aircraft pilot coupling (APC) events with undesired,largescale and oscillatory characters. Detector can identify PIO events by the signals of aircraft. The key technology of design fuzzy logic detector for PIO events is the choice of fuzzy variables and design of fuzzy inference system,and fuzzy variables are described by some membership functions. In terms of analyzing and deducing the flight's characters of PIO and fuzzy variables changing range,the membership ... |
