无人机六自由度飞行建模与仿真研究

鉴于无人机在军事和民用领域广泛的发展，用数字仿真的手段可以验证无人机在特定条件下是否达到了飞行品质的要求，进而进行半实物仿真，最后进行飞行试验。通过飞行仿真可以缩短无人机的研制周期，降低研制经费和风险。无人机六自由度飞行仿真建模研究对无人机系统的初期研究和后期模拟训练器的研制都起着重要的作用。课题组利用Simulink工具进行了无人机六自由度飞行建模仿真研究，所建立的无人机的六自由度空气动力学模型既可以进行纯数字的仿真试验，也可以为后续研制高逼真的无人机模拟训练器中无人机动力学模型设计打下基础。

UAV 6 DOF Flight Modeling and Simulation Researching

With unmanned aerial vehicle （UAV） is drawn considerable attention,due to their promising benefit in both civilian and military applications. We can use mathematics simulation methods to check up flying character, then do the hardware in loop simulation experiments, at last we can do the flying experiments. Which can reduce the periods, outlay and risk about the researching development. UAV six dregree of freedom （DOF） researching can do important action in simulation and modeling in initialize periods and traning simulator manufacture in final periods. Paper modeled six DOF UAV modeling using Simulink,UAV six DOF flight simulation model which could afford mathematics simulation experiment and do the basic researching works for the UAV training simulator in future research
