摘　　要：针对开放式四轴运动控制开发实验平台中存在的电机控制对象姿态无法直观观察问题,提出了雷达监控半实物仿真教学系统。该系统以电机为控制对象,以工控机和运动控制器为控制核心,通过控制器库函数实现了两个电机的位置与速度控制。以OpenGL建模技术建立了两自由度三维虚拟雷达,利用位置监控与定时器同步技术实现了虚拟雷达的方位轴、俯仰轴与电机的同步运动与控制。为了逼真模拟临场效果和增加教学效果,利用建模技术增加了机群模拟攻击和虚拟仪表的飞机监控功能。经测试该系统能够充分发挥实验平台的教学功能,解决其存在问题,并在实践教学中起到良好教学效果。Aiming at the problem that the object＇s posture controlled by motors cannot be observed directly in the open 4-axis motion controlling development platform,a semi-physical simulation and teaching system for radar control is proposed.With motors being controlled and IPC and motion controller as control center,the system realizes position and velocity control by library functions for controller.OpenGL modeling technology is used to build a 2-freedom 3-dimensional virtual radar,which can realize the synchronous motion and control with motors in azimuth axis and elevation axis by position monitoring and timer synchronization.To simulate the field condition and enhance the teaching effect,the functions of plane simulating attacking and virtual instrument for monitoring planes are added by modeling technology.By test,the system can fully exert the teaching function of the development platform,solve its problem and achieve good teaching effect.
