BTT导弹三维制导控制一体化建模与仿真

针对带有一定机动能力的飞行目标,结合弹目运动关系与导弹自身的动力学特性,给出了倾斜转弯(BTT)拦截导弹的俯仰、滚转、航向三通道独立制导控制一体化(IGC)设计。首先分别建立三通道数学模型,并给出了指令信号的计算形式,随后设计了基于动态面的IGC反步控制算法,最后在三维空间下进行目标拦截仿真验证。仿真结果表明,所建立的三通道模型能够充分描述目标与导弹之间的运动关系,设计的算法能够实现导弹对目标的精确拦截,且具有一定的抗机动能力。

Modeling and Simulation of Three-Dimensional Integrated Guidance and Control Design for BTT Missile

To intercept the target with a certain maneuver capability, the design of three-channel independent integrated guidance and control(IGC) for bank-to-turn(BTT) missile is presented with considering the movement between missile and target and the dynamic characteristics of missile. Firstly the mathematical model of three-channel is established and the calculation forms of the command signal are given. Then the IGC backstepping control algorithm based on dynamic surface is designed. Finally, the simulation of target interception in three-dimensional space is carried out. The simulation results show that the three-channel independent model can fully describe the motion relationship between the target and missile, and the designed algorithm can achieve an ideal miss distance with a certain anti-maneuvering ability.
