摘　　要：提出了一种激光制导半实物仿真系统。系统由软件仿真子系统、硬件在环仿真子系统和视景仿真子系统构成。软件仿真子系统基于Simulink建立了制导飞行器的运动学、动力学模型和目标的运动模型,可以完成制导飞行器的内环姿态控制和外环制导的数字仿真。硬件在环仿真子系统由工控机分别控制激光制导单元和目标模拟单元,实现制导飞行器制导的激光导引。应用基于高斯光斑的拟合改进算法提高四象限探测器对目标位置的检测精度。Simulink通过UDP通讯与LabView进行数据交互。使用AC3D建立了制导飞行器与目标的三维物理模型,基于FlightGear实现了制导飞行器和目标的联合仿真,构建了视景仿真子系统。仿真实验表明,该系统不但能够完成制导飞行器的飞行姿态控制和制导律的研究,而且能实时实现三维视景显示。In this paper,a laser guidance hardware-in-the-loop simulation system is proposed,which consists of a software simulation subsystem,a hardware-in-the-loop simulation subsystem,and a visual simulation subsystem.The software simulation subsystem establishes the kinematics and dynamics model of the guided aircraft and the motion model of the target based on Simulink,which can complete the digital simulation inner-loop attitude control and outer-loop guidance of the guided vehicle.The hardware-in-the-loop simulation subsystem is controlled by an industrial computer to control the laser guidance unit and the target simulation unit respectively,to realize the laser guidance for guided aircraft guidance.An improved fitting algorithm based on Gaussian spot is applied to improve the detection accuracy of the four-quadrant detector.Simulink communicates with LabView via UDP communication protocols.The three-dimensional physical model of the guided aircraft and the target is built with AC3D,and the co-simulation of the guided aircraft and target is achieved based on FlightGear,and the view simulation subsystem is constructed.Simulation experiments show that the system is not only capable of completing the study of the flight attitude control and guidance law of the guided vehicle,but also realizing the three-dimensional visual display in real time.
