带有高阶滑模微分器的制导控制一体化设计

Integrated Guidance and Control Design with Sliding Mode Differentiator

针对制导控制一体化模型中由于目标机动加速度难以测量的问题,提出了应用高阶滑模微分器,对导弹导引头获得的弹目相对运动信息进行微分,从而解算出目标加速度的方法。在最后开展了导弹六自由度仿真验证,将高阶滑模微分器得到的目标加速度与真实值进行对比,验证了方法的有效性。

As the target information in the integrated guidance and control model are difficult to measure, a novel high order sliding mode differentiator （SMD） is introduced to get access to the target acceleration by differentiating the target and missile relative motion information obtained from the missile active homing seeker. The six degree of freedom simulation is carried out and a comparison between the estimated target maneuver information and its true data is made, which successfully verifies the effective- ness the proposed algorithm.
