【摘要】：飞行员的训练不可能一开始直接就在空中进行,这样的话会增加训练的风险,而且这样的危险一旦发生后果将非常的严重。同时在讲授很多的基本的飞行理论的时候也是需要一个类似飞机的模型给学习者进行试验,这样就会更加有助于学习者对知识的掌握。而这样的一个模拟仿真设备就是这里需要研究的电动六自由度飞行模拟机仿真平台,这样不仅可以方便学习同时可以降低成本,使得学习更加方便。采用飞行模拟器代替实装飞机的飞行训练,可以大量节省航空燃料,减少燃烧尾气和二氧化碳的排放量,环保效益巨大。目前我国整个民航业现有的飞行模拟机都是从国外进口的,制造模拟机必须提供飞机的飞机参数、飞行数据、性能参数、动力学性能等资料,也就是国外完全掌握我国民用飞机的技术状况,既化费了大量资金、又泄流了技术机密。所以对电动六自由度飞机模拟机的研究具有很高的价值,对我国未来的大飞机发展具有非常重要的影响。飞行模拟机在飞行的过程中,在实现各个动作的过程中,给试飞人员带来的动态感觉是最重要的,如果在飞行模拟机上飞行的感觉与真实的飞机飞行的感觉能够越来越接近,才能说明模拟机的效果越好。为此,缩小模拟飞行感觉与真实飞行的感觉差距,是衡量模拟机性能的重要参数,也是重点和难点,也是未来该领域需要重点研究和解决的问题。针对以上提出的问题,本文将从经典的控制方法出发,研究基于模糊控制理论的六自由度飞行模拟机洗出滤波控制方法的优化,使得模拟机带给飞行员的飞行动感与真实飞机飞行的动感在原来的基础上更加的接近,给试飞人员带来更好的动感体验。本文将通过分析、实验等多种方法对飞行的参数进行优化,最后使用MATLAB软件设计SIMULINK框图,并且进行仿真得到的飞行曲线与传统的曲线进行比较,得出在优化后的曲线与真实飞行的动感更加的接近,最终将优化后的结果在模拟机上进行试飞和验证。
[Abstract]:Pilot training cannot be carried out directly in the air from the start, which increases the risk of training, and if such a danger occurs, the consequences will be very serious. At the same time, many basic flight theories are taught and a model similar to aircraft is also needed for learners to experiment, which will be more helpful for learners to master knowledge. Such a simulation and simulation equipment is the electric six degrees of freedom flight simulator simulation platform, which can not only facilitate learning, but also reduce the cost, make learning more convenient. Using flight simulator instead of aircraft flight training can save a lot of aviation fuel, reduce emissions of combustion exhaust and carbon dioxide, and have great environmental benefits. At present, the existing flight simulators in the entire civil aviation industry in China are imported from abroad. The flight parameters, flight data, performance parameters, dynamic performance of the aircraft must be provided for the manufacture of the simulators. In other words, foreign countries have fully mastered the technical situation of China's civil aircraft, which not only cost a lot of money, but also leaked technical secrets. Therefore, the research of electric six degrees of freedom aircraft simulator has a high value, and has a very important impact on the future development of large aircraft in China. During the flight of the flight simulator, the dynamic feeling to the flight tester is the most important in the process of realizing the various movements. If the feeling of flying on the flight simulation plane can be more and more close to that of the real plane, To show that the better the effect of the simulator. Therefore, narrowing the gap between simulated flight sensation and real flight is not only an important parameter to measure the performance of simulator, but also an important and difficult point. It is also a problem that needs to be studied and solved in this field in the future. In view of the above problems, this paper will study the optimization of washing out filter control method based on fuzzy control theory, which is based on the classical control method. The flight motion of the pilot brought by the simulator is closer to that of the real flight, which brings a better dynamic experience to the flight test personnel. In this paper, the flight parameters are optimized by analysis, experiment and other methods. Finally, the SIMULINK block diagram is designed by using MATLAB software, and the flight curve obtained by simulation is compared with the traditional one. It is concluded that the optimized curve is closer to the real flight motion, and the optimized result is tested and verified on the simulator.
