导弹跟踪末制导控制方法研究

Research the Method of Missile Tracking Flight in End-game

根据导弹在跟踪接近目标时对响应时间和精度的要求,用输入-输出的线性化来近似研究导弹的非线性运动控制,重点对导弹制导控制过程中的线性化控制方法进行了研究和数学推导。针对导弹制导过程中的非线性控制问题,用消除内反馈和零点的方法,近似线性化地来研究导弹的非线性运动控制,然后通过自适应控制保证了马赫数和质量在较大范围(35%)内变化时系统的响应精度和稳定性。将该方法应用于导弹跟踪飞行控制,通过计算机仿真,效果好。

In this paper,in order to meet the requirement of track target in missile endgame,input-output approximate linearization of a nonlinear missile has been studied.A method for controlling the nonlinear system that is input-output linearization is produced with no internal or zero dynamics.Desired tracking performance for lateral acceleration of the missile is achieved by using a nonlinear control law that has been derived by selecting the lateral velocity as the linearization output.Then an adaptive nonlinear...
