【摘要】 微型飞行器(简称MAV)是飞行器新兴的发展方向，国内外在研的MAV有20多种，气动布局形式多种多样，但哪种气动布局最适合于HAV还仍无定论，且控制问题是MAV研究中最具有挑战性的关键技术问题，由于MAV体积小、质量轻，传统的控制方案对于MAV已不太适合，而基于MAV气动外形形变的姿态控制方案是一种新颖的先进控制策略，可望填补MAV控制问题研究领域的空白。本文旨在对各种气动布局的MAV进行气动特性比较分析与综合，得出最适合于MAV的原型机，在建立一套基于气动外形形变的性能研究环境的基础上，对该原型机进行气动外形形变先进控制策略的探索。 本文针对MAV的具体特点，抽象出MAV的气动工程计算数学模型，建立起气动工程估算环境，对各种气动布局进行了气动特性比较分析与综合，寻求出理想的MAV气动布局方案并提出MAV原型机，抽象出基于涡格法的气动外形形变的数学模型，建立起气动外形形变性能研究环境，探讨新型的飞行控制方法和气动力控制策略，在得出气动外形形变模型的初始方案后，对其进行进一步的优化，最后得出理想的气动外形形变执行机构组合阵列。 本文的研究工作是在国家自然科学基金项目——基于气动外形变形的MAV控制问题研究(编号为60175032)的资助下开展的，是进行MAV新颖控制方案研究的基础性工作。更多还原

【Abstract】 MAV represents a newly developing direction of aircraft, at home and broad, there are more than twenty kinds of MAV in research, the configuration is many and varied, but the problem about which kind of configuration is fit for MAV still have no conclusion being drew. What’s more, the control technique is the most challenging issue of MAV. Because of the tiny volume and little mass of MAV, the traditional controlling scheme hasn’t been so suitable. Instead, the controlling according to attitude-controlling of the deformation of aerodynamic configuration is new and advance measure, which has great probability to supply the gap in researching of the control technique of MAV. This paper aims that three varied configurations of Micro Air Vehicle will be designed and Optimized, then their aerodynamic property will be compared and analyzed, And the prototype of MAV will be got. On the base of the soft about the deformation of aerodynamic configuration of MAV, the advanced controlling technique of the deformation of aerodynamic configuration about the prototype MAV will be explored.Based on the characteristic of Micro Air Vehicle, this paper abstracted the aerodynamic evaluation mathematics models, developed a aerodynamic engineering estimation program, all kinds of aerodynamic configuration was compared and analyzed, found the perfect configuration and got the prototype of MAV. Abstracted the model about the deformation of aerodynamic configuration on base of the method of vortex lattice, developed the program for researching the performance of the deformation of aerodynamic configuration. Explored the new scheme of the method of flight control and aerodynamic control. After getting the original project of the model of the deformation of aerodynamic configuration, which will be optimized further. Lastly get the optimized Innovative control effectors of the deformation of aerodynamic configuration.The research in this paper is granted by the item of National Natural Science Foundation of China, the research of MAV control base deformation of aerodynamic configuration (NO:60175032), it is the ground work of developing innovative control scheme.更多还原
