中文摘要:

      为了提高动态复杂环境下飞机驾驶舱人机系统的安全性，提出一种基于负荷均衡的动态功能分配方法。结合飞行任务和飞行员生理特征预测飞行员的工作负荷，将预测结果作为动态功能分配的触发条件，基于模糊推理调整驾驶舱自动化等级，实现飞行任务在飞行员和自动化系统之间的协调分配。基于Simulink建立飞行任务需求、飞行员生理特征、飞行员工作负荷预测、模糊推理、任务分析与再分配模块，通过仿真测试对提出的方法进行分析和验证，结果表明该方法能够及时有效地调整任务分配，避免飞行员工作负荷过高或过低。

英文摘要:

      In order to improve the safety of cockpit man-machine system in dynamic complex environment,a dynamic function allocation method based on load balancing is proposed.The workload of pilots is predicted according to the flight task and physiological characteristics of pilots.The prediction results are used as the trigger conditions of dynamic function allocation.The cockpit automation level is adjusted based on fuzzy reasoning,and the coordinated allocation of flight tasks between pilots and automation systems is realized.Based on Simulink,the modules of flight task demand,pilot physiological characteristics,pilot workload prediction,fuzzy reasoning,task analysis and redistribution are established.The simulation results show that the proposed method can adjust the task allocation timely and effectively,and avoid the pilot workload too high or too low.
