基于跟踪补偿任务的飞行员感知模型

Pilot perception model based on tracking compensation task

针对飞行员对外部信息的多通道感知特点,建立了基于跟踪补偿任务的飞行员感知模型,模型具有视景和前庭系统反馈.通过对飞行员感知特性的深入分析,利用视景系统的外部特征和前庭器官的生理结构建模,结合俯仰跟踪任务,利用最小二乘法对模型进行参数辨识,并在降落和起飞两个飞行工况中对模型进行了验证.试验表明,在跟踪补偿飞行任务中,飞行员控制行为模型的仿真输出曲线与飞行测试数据之间的高度误差小于3.5 m,俯仰角误差小于1.5°,说明建立的飞行员感知模型能够较好地反应飞行员的感知特性.

Aimig at the multi-channel perception characteristics of a pilot for the external information,a pilot perception model based on tracking compensation task and with visual and vestibular system feedback was established.Through analyzing the perception characteristics of pilot,the external characteristics of the visual system and the physiological constitution of the vestibular apparatus were utilize to establishe the model.In combination with the pitch tracking task,the parameter identification of the model was carried out with the least squares method.In addition,the model was validated in both flight conditions of taking off and landing.The results show that in the tracking compensation task,the height error between the simulating output curves of the pilot control behavior model and the flight test data is less than 3.5 metres,and the error in the pitching angle is less than 1.5°.It indicates that the established pilot perception model can better reflect the perception characteristics of pilot.
