An Unmanned Aerial Vehicle Simulation System with JTIDS Interface

建立了一个具有联合战术信息分发系统接口的无人机仿真系统。在该系统中建立了某型无人机的动力学仿真模型,其气动系数均通过风洞试验获得,并采用单纯形调优法求取无人机初始状态;设计了控制无人机姿态和控制飞行轨迹的内外环控制系统模型;根据联合战术信息分发系统特性,采用模块化方法建立了联合战术信息分发系统接口,使操作员能通过仿真数据链对无人机动力学模型进行任务控制和状态监视。最后进行了虚拟任务仿真试验,结果表明该系统可以满足一定的战术任务需求。

This paper presents a simulation system of UAV（Unmanned Aerial Vehicle）with JTIDS（Joint Tactical Information Distribution System） interface.In this system,a mathematical dynamics and kinematics model of UAV is introduced,in which the pneumatic coefficients are obtained by the wind tunnel test and the initial state of the UAV is gotten through the simplex research arithmetic.The mathematic model for inner and outer control loops of the UAV is proposed,where the inner loop is to control the UAV attitudes and the outer loop is to control UAV flight trajectory.According to the characteristic of JTIDS,JTIDS interface is introduced to the system by means of modularization,thus the operator can control and watch the UAV through simulative data link.Simulation experiment for virtual mission is conducted,and the results show that this simulation system can meet the requirement of UAV tactical mission.
