| 中文摘要 |
| 针对存在参数不确定性和外扰的飞行器再入姿态控制问题, 提出一种基于准连续高阶滑模的控制方案. 首先基于奇异摄动理论将姿态控制系统分为快、慢两回路; 随后在慢回路滑模控制系统设计中利用范数型切换函数代替符号函数以使虚拟控制量平滑连续; 在快回路设计中, 基于积分型快速终端滑模、反馈控制和准连续高阶滑模控制理论设计快回路控制系统. 理论分析和仿真结果均表明, 该控制方案在增强系统鲁棒性的同时能够有效削弱系统抖振. |
| 英文摘要 |
| We propose a quasi-continuous higher-order sliding mode control strategy for the re-entry vehicle in the presence of parameter uncertainties and external disturbances. This attitude control system is divided into fast loop and slow loop based on singular perturbation. The sign function is replaced by the norm-type switching function for the continuous virtual control in the slow loop. The fast loop consists of the integral fast terminal sliding mode control, the feedback control and the quasi-continuous higher-order sliding mode control. Theoretical analysis and simulation results show strong robustness and weak chattering. |
