| 摘 要： | 针对机动目标拦截问题，应用高阶滑模控制方法，设计了高精度制导律。在制导律设计过程中，针对目标机动，基于增广比例导引设计了滑模变量，考虑二阶弹体动态特性，设计了二阶滑模制导律。应用高增益扩张状态观测器对制导信息进行估计，完成了制导律的实现。数值仿真结果验证了方法的有效性。

| Abstract: | For the interception of maneuvering targets, a high precision guidance law is designed using higher order sliding mode approach.In the guidance law design, to cope with the target maneuver, sliding variable is designed based on augmented proportional navigation.Considering the second order missile dynamics, second order sliding mode guidance law is designed.In the guidance law implementa-tion, high gain extended state observer technique is used to estimate guidance information.Numerical simulation results show the effectiveness of the proposed method. |
