摘　　要：针对驾驶员完成飞机纵向速度和俯仰角的跟踪任务 ,对双通道人 机系统中驾驶员描述函数的识别方法进行了系统的研究 .通过驾驶员描述函数识别结果和线性相关性分析 ,提出了一种双通道控制时驾驶员描述函数识别的简化方法 .将双通道人 机系统近似分解成两个单通道系统 ,并从理论和实验两方面验证了这种近似方法的可行性 .该方法对双通道人A simplified methodology is described for identifying human pilot describing function in a two axis control task. A real time simulation is carried out on simulator, in which pilot tracts the command velocity and pitch angle of aircraft by controlling the stick and throttle respectively. Coherence functions between the two axis show a weak coupling in this task. This suggests it is possible to treat the two axis control system as two single axes respectively for the pilot model identification for the longitudinal control task. The feasibility and rationality of simplified methodology is demonstrated in both theory and simulation experiment for the control task.
