摘　　要：无人机飞控系统是无人机模拟训练系统的一个重要组成部分。基于某型无人机实飞参数,解出发动机推力,建立了发动机动力学模型,并结合无人机六自由度模型建立了无人机飞行仿真模型,对该型无人机模拟训练系统飞控系统的研制具有重要意义。最后在MATLAB/SIMULINK环境下进行了仿真,结果表明该建模方法是正确的。Flight control system is an important part in UAV simulation training system.Based on several known flight parameters of a UAV,engine thrust force is calculated,a way of building engine dynamics model is put forward and a flight simulation model is established linked with six-DOF mathematical model.Lastly a simulation is carried out with the environment of MATLAB/SIMULINK,and the simulation result proves the model to be usable,thus of great value for the manufacturing of UAV simulation training system.
