针对激光驾束制导导弹抗侧风干扰问题,基于减载控制思想,提出了一种通过控制气流侧滑角的大小来实现姿态修正的方案。在不增加弹上设备的前提下,由惯组信息估计得到实时气流侧滑角,进而将其反馈到控制回路,通过调节修正系数来抵抗侧风造成的导弹横向过载。六自由度仿真结果表明,在24 m/s的侧风干扰下,不加侧风修正方案的导弹会脱离激光波束,而改进方法的制导线偏差则快速收敛,脱靶量小于0.1 m,证明了该方法的有效性。
Aiming at the crosswind resistance of laser beam guidance missile, based on the idea of load shedding control, a scheme of attitude correction is proposed by controlling the size of air flow side slip angle. The real-time airflow side slip angle is estimated from the information of the weaker group without increasing the equipment on the bomb, and then fed back to the control loop. By adjusting the correction coefficient, the lateral overload of the missile caused by crosswind is resisted. Six degrees of freedom simulation results show that the missiles with no sidewind correction scheme will be out of the laser beam under 24 m / s sidewind disturbance, while the improved method of the guidance line deviation converges rapidly with the miss distance less than 0.1 m, proving The effectiveness of this method.
