采用状态反馈实现极点配置的导弹过载控制系统设计

Design of Overload Control System of Missile by State Feedback to Match the Poles

给出了一种新的导弹过载控制设计方法。首先，对导弹的控制模型进行数学处理，得到以舵偏角速度为控制量的导弹控制模型的状态方程表示；然后，采用状态反馈极点配置方法设计了以舵偏角速度为控制量的控制规律，再通过积分，得到真正的舵偏角控制信号。与现有各种方法所不同的是．本文方法用到了角加速度的反馈，而没有用到角速度的反馈。设计分析和仿真计算表明，本文新方法控制效果好，且较便于工程实现。

This paper introduces a new method to design the overload control system of missile. First, the control mode of missile is disposed mathematically, and the state equation of the mode, whose command is angle rate of the rudder, is given. Then, the control law is designed by state feedback, and the real command of angle of the rudder is gotten by integrating the control law. Different from the existing design, this design .uses the feedback of angle acceleration other than the feedback of angle rate to get the command. Analysis of design and results of Simulation show that this new design is effective and easy to realize in practice.
