摘要: 在眼动系统中,由于视网膜中央凹区域受到噪声的干扰,使得眼跳时间和准确度不能同时达到最优化。为了得到最优眼动轨迹,在权衡眼跳时间和准确度的基础上,从眼动消耗最小入手,应用最优控制理论和Pontryagin极小值原理,提出了最优眼动控制模型;并利用眼动主序关系对此模型进行了分析;结果表明,任何给定的眼跳幅度条件下,都有唯一的最优眼跳时间使眼动总消耗达到最小,并且此时的眼动轨迹为最优眼动轨迹。该模型对优化飞行员、管制员等工作人员的眼动策略和眼动轨迹具有一定意义。

Abstract: In eye movement mechanism, retinal fovea area is perturbed by the noise, which makes the movement duration and accuracy fail to reach optimization at the same time. Aiming to obtain the optimal eye movement trajectory, considering weight of duration and accuracy, and from the perspective of minimal cost of eye movement, an optimal control model of eye movement based on optimal control theory and the Pontryagin minimum principle is proposed in this study. Meanwhile, the relationship of eye movement main sequence is used to analyze this model. The result shows that there is a unique optimal duration for a given amplitude which makes eye movement to minimize the total cost, and the eye movement trajectory is optimal. The model is meaningful to optimize eye movement strategy and eye movement trajectory for the pilot, controller and other staff.
