Model and Simulation of Pilot Vehicle System in Multi Axis and Multi Loop Task

针对驾驶员完成飞机进场下滑过程的多轴多回路控制任务，分析了人的控制行为特点，确定出驾驶员的信息反馈，形成了人机系统的闭环控制结构。根据驾驶员对各控制回路的注意力分配和人机自适应规律性，选择相应的驾驶员模型形式并确定其参数，建立了多轴多回路的人机控制系统模型。最后，对风切变大气环境下驾驶员控制的飞机进场下滑过程进行了仿真计算，结果表明，所建立的人机控制系统模型是合理的，对飞行品质研究有参考价值。

A final landing approach mission is assigned to pilot to investigate model and simulation of pilot vehicle system in multi axis and multi loop task.The closed loop model of human pilot in the task is established based on pilot behaviors in the mission.According to man machine adapting characteristics and pilot attention distributions in several closed loops,we select pilot models respectively in the loops and evaluate parameters of the pilot models.Using the closed structure of pilot aircraft system,an approach process is simulated in wind shear condition.The results illustrate that the established model of pilot aircraft system is reasonable and can be used to analyze aircraft handling qualities.
