摘要

针对最优控制先导模型(OCM)中权重矩阵的计算问题,提出了一种基于先导最优注意力分配假设的权重计算方法。通过数值算例验证了最优注意力分配假设和权重计算方法,证明了假设的合理性和权重比计算方法的可行性。通过仿真得到三个主要结论:第一,指标函数的形式对人机系统的频域特性有显著影响;第二,虽然指标函数设置不同,但得到的观测权重值Qy基本相同,这可能表明飞行员对同一架飞机的同一任务的注意力分配基本相同;第三,当指标函数中的观测因子大于2时,可能没有解,也可能有多组解。这种方法可能是无效的,这将在未来进一步深化。

A Method for Generating the Weighting Matrixes in Optimal Control Pilot Model
To solve the problem of the weighting matrixes calculation in Optimal Control Pilot Model (OCM), a weightings calculation method based on pilot's optimal attention allocation hypothesis is proposed. A numerical example is used to verify the hypothesis of optimal attention allocation and the method of calculating the weightings, which proves the rationality of the hypothesis and the feasibility of the weighting ratio calculating method. Through simulation, three main conclusions are obtained: first, the form of index function will significantly affect the frequency domain characters of the man-machine system; second, although the index function is setting differently, the obtained observation weightings values Qy are basically the same, which may indicate that the pilot's attention allocation is basically the same for the same mission of the same aircraft; third, When the observation factors in the index function is larger than two, there may be no solution or multiple groups of solutions. This method may be ineffective, which will be further deepened in the future.
