摘　　要：针对大角度攻击武器快时变非线性特性和传统PID控制参数难于调节的矛盾,提出了一种基于降阶线性扩张状态观测器的线性自抗扰PD控制方法,采用一组控制参数即完成了大角度攻击导弹俯冲段姿态控制设计。设计过程和弹道仿真表明,提出的方法控制参数调节简单,姿态指令跟踪良好。Because the weapon in attack with high angle is usually time-varying fast nonlinear,the controller parameter is difficult scheduled with conventional PID control.Therefore,a linear active disturbance rejection control approach based on deduced-order linear extended state observer is proposed,which is applied to design on the attitude control for the dive section of the weapon in attack with high angle only with a set of controller parameters.Both controller design and ballistic simulation show that the presented approach has easiness on scheduling controller parameter and good capability on tracking attitude command.
