旋转导弹等效合力在线自适应补偿方法研究

Online Adaptive Compensation Method for Equivalent Force of Spinning Missile

针对旋转导弹舵系统在偏转过程中出现的相位滞后和幅值畸变,给出了一种在线自适应补偿方法。介绍了旋转导弹的控制原理,并对其等效合力畸变的机理进行分析,同时对传统的补偿手段在工程实际中遇到的问题展开说明。在此基础上提出了一种不基于精确模型的等效合力自适应补偿方法,该方法利用输入信号和实际输出之间的偏差形成闭环反馈,通过合适的补偿算法实现对等效合力大小和方向的准确补偿。最后通过数字仿真对比分析,检验了该方法的有效性。

This paper presents an adaptive compensation method for the phase lag and amplitude distortion of the rudder system of a spinning missile in the course of deflection.This paper introduces the control principle of the rotary missile,then the mechanism of the equivalent force distortion is analyzed and the problems that the traditional compensation method encounters in engineering practice are explained.Secondly,this paper designs an adaptive compensation method which is not based on an exact model.This method uses the deviation of the input signal and the output signal to form the closed-loop feedback,and compensates the equivalent force with an appropriate algorithm.Finally,the validity of this method is verified by means of the digital simulation comparison.
