2017年北航-清华-北大三校“歼十杯”博士生学术文化节即将于本周末在顺鑫绿色度假村举行。来自北京航空航天大学ld乐动体育官方网站的冯传宴和范思儀同学将带来关于各自研究课题的宣讲。
范思儀同学的报告题目是《基于流体扰动的农业植保无人机航路规划》。
报告内容是：根据直升机机动特性，提出一种面向农业植保领域，基于流体扰动动态系统的航路规划方法。通过样例直升机参数，确定最大升限、爬升性能、前飞速度等机动特性；建立障碍物等效模型，将其量化为扰动矩阵并修正初始流场产生新航点，同时结合已确定的机动特性，针对不同的障碍物类型作出不同避障策略。仿真结果表明该方法可实时高效产生平滑可飞的航路，使无人植保直升机自主躲避农田间常见障碍物并完成植保任务。
冯传宴同学的报告题目是《A comprehensive prediction and evaluation method of pilot workload》。
报告内容是：The prediction and evaluation of pilot workload is a key problem in human factor airworthiness of cockpit. A pilot traffic pattern task was designed in a flight simulation environment in order to carry out the pilot workload prediction and improve the evaluation method. Also, a typical flight subtask and a dynamic workload (cruise, approach, and landing) prediction was built up based on multiple resource theory, and a favorable validity was achieved by the correlation analysis verification between sensitive physiological data and the predicted value. Then, a statistical analysis of physiological indices during typical workload status was prepared. At last, in order to discriminate the three typical workload conditions, a multinominal logistic regression model based on combination of physiological indices (fixation frequency, mean normal-to-normal interval, the ratio between low frequency and sum of low frequency and high frequency, and mean tonic) was constructed, and the discriminate accuracy was comparatively ideal with a rate of 84.85%. Our study can provide specific theoretical foundations and methods for pilot workload prediction and evaluation.
