摘　　要：以某型低速无人机为例,使用Digital Datcom计算机程序对某型无人机进行气动参数估算,将所得气动参数导入Matlab,然后搭建无人机的Simulink模型、包括环境模型、动力系统模型、执行机构模型和空气动力学模型,以及六自由度运动方程模型,并使用串级PID进行无人机纵向飞行控制器设计,对控制器进行参数整定。利用AC3D软件和xml修改并配置无人机的Flightgear模型,将仿真模型用Matlab-Flightgear联合进行无人机的动力学解算和实时三维视景仿真。In this paper,aerodynamic parameters of a conventional unmanned aerial vehicle(UAV)was estimated by Digital Datcom computer program and imported into Matlab. Simulink model of the UAV was further established,which included environment model,power system model,actuator model,aerodynamic model and six-degree-of-freedom motion equation model. Longitudinal flight controller of the UAV was also designed based on series PID to tune the parameters of the controller. In addition,Flightgear model of the UAV was modified and configured by AC3 D software and. xml. Finally,the dynamic calculation and real-time three-dimensional scene simulation of the UAV were carried out by combining Simulink model with Flightgear model.
