摘　　要：构建了巡航导弹动力学模型,将不确定性项与风浪干扰项合并,同时引入一种自适应干扰观测器予以补偿,提高导弹控制系统的鲁棒性,并利用高阶滑模控制器和任意阶微分器实现控制系统反馈环节的有限时间镇定.仿真实验表明,该方案可实现在1∼7级海况下巡航导弹掠海飞行的高精度轨迹跟踪,同时具备较高的收敛速度和良好的适应性.This study evaluates a sea-skimming cruise missile tracking control system using higher order sliding mode(HOSM)control based on an adaptive disturbance observer.Feedback control with finite time convergence was realized using a HOSM controller and differentiator.To increase the robustness of the control system,an adaptive disturbance observer was utilized to compensate for marine disturbances and aerodynamic fluctuations.These disturbances are merged into the unmatched external disturbance via the transformation of the cruise missile dynamics.A simulation was performed under various sea conditions to verify the high accuracy tracking and the robustness of the proposed scheme.
