导弹姿态控制系统分布式仿真研究

On distributed interactive simulation of missile's attitude control system

以某型地地导弹为研究对象,简要介绍了导弹姿态控制系统的功能、原理及分布式仿真方法,并根据导弹姿态控制系统组成特点搭建了分布式仿真回路,回路由嵌入式计算机和现场总线组成。仿真回路包含5个结点,结点之间通过CAN总线连接。在此基础上进行了导弹姿态控制系统分布式仿真试验,对导弹整个主动段的飞行姿态进行了仿真计算,并对仿真结果进行了分析,证明导弹在整个主动段的飞行运动是稳定的。试验也验证了数据在总线上传输的可靠性。

The function and composition of the attitude control system for a certain type of missile are introduced. A distributed simulation loop is built based on PC/104 and CAN bus according to the characteristics of missile's attitude control system. There are 5 nodes in the simulation loop, which are connected by CAN bus. Simulations were taken for attitude control system of the missile, and calculations were made for the active phase flight attitude of it. The result was analyzed. It showed that the missile's flight in its active phase is stable, and the data transmission on bus is reliable.
