摘要:

针对某静不稳定导弹,建立了导弹纵向运动模型,运用最优控制理论设计了俯仰通道三回路过载控制系统,然后采用了simulink参数寻优的方法对回路参数进行优化,对设计出的控制器进行了特征点仿真。结果表明,三回路过载控制方法能较好的控制静不稳定导弹,优化后的控制系统能使导弹具有更快的跟踪性能、更好的机动能力,并且舵机没有产生严重的饱和现象。

Abstract:

A missile longitudinal model was established to a static unstable missile and the three loop acceleration control on longitudinal was designed based on the theory of optimal control. Then the method of simulink parameters optimizing was used to optimize the control parameters and simulate the control system that we designed at the characteristic flying point. And the result show that the three loop acceleration control can control the unstable missile quite well. The optimized control system performance is good than the original control system at the control speed and flying agility and there is no saturation of rudders.
