弹道修正弹模糊自适应PID控制器设计

Trajectory Correction Projectiles Fuzzy-PID Controller Design

弹道修正弹是一种在头部安装修正引信的低成本、高精度、远射程的精确打击弹药,它在飞行过程中可以通过实时控制提高命中率;介绍了修正弹修正方式,建立了弹体动力学模型,应用模糊控制与传统PID控制理论相结合的方法,设计了控制器并对弹道特征点俯仰通道进行仿真,结果表明模糊自适应PID控制器能够适应弹道修正引信,且比传统PID控制器有更好的控制效果。

As a new type of precise attacking weapon, the trajectory correction projectiles find favor in more and more eyes for their low price and attacking precision. It can correct the trajectory by controller during its flight. This paper introduces the correction method, uses the dynamic model, and combines the fuzzy control and PID theory to build controller. Controller was designed and ballistic characteristics point was simulated. The results show that the fuzzy adaptive PID controller can adapt to the trajectory correction fuze, and the control effect is better than the traditional PID controller.
