项目摘要

The optimal control of an aircraft under the gust winds is investigated in order to establish safety landing and take-off operation of an aircraft. The purposes of this research are summarized as follows ; (1) the establishment of an estimation method of wind vectors acting on a flying aircraft, (2) the determination of control method of an aircraft under the gust winds using an optimal control theory, (3) the investigation of a worst case wind profile against a pilot control of an aircraft, and (4) the confirmation of the research results using a flight simulator which is constructed for this research purpose. Firstly, the wind simulator is designed to make arbitrary wind profiles and to analyze flight results. Secondly, a fuzzy multi-goal programming method is developed to construct a decision model of a human pilot. This method is applied to propose the safe operation of a take-off aircraft under a micro-burst wind. Furthermore, the wind vector estimation method is developed by using accelerometer data of a flying aircraft and the usefulness of the proposed method is confirmed by analyzing both flight simulation data and real flight data. Additionally, the worst case wind profile is studied by using the game theory which introduces an intelligent wind against a aircraft pilot. The numerical results make clear that the micro-burst type wind is the worst wind profile against a controlled aircraft. Finally, recent aircraft accidents caused by the gust wind are investigated to examine the future technological trends.

为了建立飞机的安全起降操作，研究了飞机在阵风条件下的最优控制问题。本研究的目的总结如下：(1)建立作用于飞行飞机的风矢量估计方法；(2)利用最优控制理论确定飞机在阵风条件下的控制方法；(3)针对飞行员控制飞机的最坏情况风廓线的研究；(4)利用为此研究目的而构建的飞行模拟器对研究结果进行验证。首先，设计了风模拟器，用于制作任意风廓线并对飞行结果进行分析。其次，采用模糊多目标规划方法构建了人类飞行员的决策模型。应用该方法对微爆风条件下起飞飞机的安全运行进行了研究。在此基础上，提出了一种基于飞行飞行器加速度计数据的风矢量估计方法，并通过对飞行仿真数据和实际飞行数据的分析，验证了该方法的有效性。在此基础上，利用博弈论引入智能风对飞行员的影响，研究了最坏情况下的风廓线。数值计算结果表明，微爆型风是对受控飞机最不利的风廓线。最后，研究了近年来由阵风引起的飞机事故，以研究未来的技术趋势。
