驾驶员结构模型参数辨识

IDENTIFICATING THE PARAMETERS OF PILOT STRUCTURAL MODEL

给出一种驾驶员结构模型的参数辨识方法：根据人—机实时仿真试验测量的驾驶员描述函数，按最小二乘准则辨识驾驶员模型参数。推导出驾驶员结构模型的灵敏度公式，用于参数辨识过程，使计算方便、收敛性改善。针对驾驶员完成俯仰跟踪任务的人—机仿真试验结果，进行了实例计算。

A parameter identification method of pilot structural model is presented, which is based on the real time simulation experiment of a pilot aircraft system. The pilot description function is measured from the experiment results of the pilot-aircraft simulation. Then parameters of the pilot structural model are identified in accordance to the least squares estimator, in which a sensitivity formula of the pilot model parameters is developed in order to improve the parameter algorithm. An example is implemented on condition that the controlled objector model is the longitudinal equivalent model of aircraft for a compensatory tracking task. The example and results indicate that the method is effective for the parameter identification of the pilot structural model.
