摘　　要：以弹性体导弹为研究对象,采用导弹在刚体运动和弹性振动的耦合模型,通过加入了干扰项构建了一个带干扰的导弹运动模型.而后采用一种改进的辅助变量方法构建了新的增广误差系统,基于此增广误差系统,将系统的预见跟踪控制转化为增广系统的调节问题.最后基于鲁棒控制理论,Lyapunov稳定性理论和LMI方法得到了预见跟踪控制器,并且证明了系统在此控制系统下是渐近稳定的,即导弹可以沿预定的弹道稳定飞行,进而精确打击目标。In this paper,the elastic body missile is taken as the research object,and the missile’s coupling model of the rigid body motion and the elastic vibration is adopted,and the jamming term is creatively joined to construct a missile motion model with interference.Then an improved auxiliary variable method is used to construct a new augmented error system.Based on this augmented error system,the predictive tracking control of the system is transformed into an augmented system.Finally,based on the robust control theory,Lyapunov stability theory and the LMI method,the foreseeable tracking controller is obtained,and it is proved that the system is asymptotically stable under this control system,that is,the missile can fly steadily along the predetermined trajectory and then strike the target accurately.
