为提高火箭弹的打击精度,设计了一套低成本制导火箭弹飞行控制系统。该系统结合GPS/INS组合导航技术,能够按照目标弹道对火箭弹的实际飞行弹道进行修正控制,以提高落点精度。为验证系统性能,还建立了制导火箭弹的实时仿真模型,控制算法可以加载到实物中进行半实物仿真实验,以优化控制参数,完善控制算法。经试验检验,该系统运行稳定可靠,控制精度高,具有工程应用价值。

In order to improve the strike accuracy of rocket, a kind of low cost flight control system for guided rocket is designed. Combined with GPS/INS integrated navigation technology, it can modify the gliding trajecto ry of guided rocket according to target trajectory to improve the impact point accuracy. To verify the system per formance, a real-time simulation model of guided rocket is established. The control arithmetic can be loaded in to flight control computer to achieve hardware-in-the-loop simulation, which makes contributes to the modifica- tion and optimization of the control software. Experiments eventually show that the system can run stably and reliably, and has high control accuracy while having engineering applicable value.
