制导炸弹大空域下的动力学模型

Dynamics Model for a Guided Bomb in Huge Airspace

针对惯性导航/卫星定位方式制导炸弹在大空域下的工作过程和特点,建立了空中的运动数学模型,分析了大空域下制导炸弹运动的非线性因素,并在线性化模型的基础上,发展了一种时变的非线性模型来描述制导炸弹大空域下飞行动力学系统的方法。最后进行了仿真,结果表明,该方法是合理的,为后续制导炸弹控制系统的自适应设计与仿真提供了参考。

According the characteristics and working process of the GB with INS/SPS （inertial navigation system and satellite positioning system）, this paper models a proper moving model, and analyzes nonlinear factors which affect GB＇s movement in huge airspace. What＇s more, the method is developed that a nonlinear time-variable model to describe the GB＇s dynamics system on the basis of the linearizing model. Finally, the simulation is available for reference to designing an adaptive control system
