无人机飞行训练仿真系统设计与实现

Design and Implementation of UAV Flight Training Simulation System

为了使领航人员更形象直观快速熟练地操控无人机按预定航路飞行,通过对前苏联体制坐标系下无人机的12阶非线性微分方程数学模型进行分析和研究,利用VC++6.0编程和网络技术实现了无人机飞行的计算机仿真。针对无人机实际飞行情况,仿真系统逼真地模拟了操作手战位和领航员战位情景,并通过网络传递信息。除了讲述系统的组成和各主要功能模块外,还提出了通过对无人机的实际飞行数据和仿真数据进行比对来修正和补偿数学模型中相关参数的方法,从而使仿真结果更趋于真实可信。结果表明,系统设计合理,功能齐全,符合实际飞行规律,可以使领航人员迅速掌握领航要领。

The simulation of the flight of UAV is implemented based on the study and analysis of its governing non - linear differential equations of order 12 in Russian coordinates with VC ＋ ＋ 6.0 program and network technology to make the pilot visually control the UAV more skillfully and quickly. The simulation system simulates the scenes of stations of the pliot and the operator realistically according to the flight actuality of UAV. It transfers information through networks. Apart from the system composition and the function of main models, a method for the calibration and compensation of parameters of the mathematical model is presented by the comparison between the data of actual flight and that of simulation to make the results more authentic. The results indicate that the simulation system is properly designed and has complete function. It is constistent with the actual flight law and can help the pilot learn the essentials of pilotage quickly.
