Research on Real-time Control System of Missile Flight Simulation

文中完善了弹箭飞行仿真的实时控制系统,进而能够保证精确的定时和数据的同步,对提高飞行仿真系统的逼真度具有重要意义。目前应用最广泛的Windows操作系统,其实时性较差,将其作为弹箭飞行仿真的控制系统,会存在控制飞行的不确定性等问题。文中在Windows操作系统内核下引入RTX实时控制系统,完善了 Windows的实时控制性能,并对此进行试验验证。结果表明:该设计方法可以满足在Windows操作系统下弹箭飞行仿真的实时控制要求。

In this paper, the real-time control system of missile and rocket projectile flight simulation is improved to ensure accurate timing and data synchronization, which is important to improve the fidelity of flight simulation system. At present, the most widely used Windows operating system has poor real-time performance. As a control system of missile and arrow flight simulation, there will be uncertainties in control flight and other problems. In this paper, RTX real-time control system is introduced under the kernel of Windows operating system, which improves the timely control performance of Windows and is verified by experiments. The results show that the design method can meet the real-time control requirements of missile flight simulation under Windows operating system.
