| 摘 要： | 运载火箭在飞行过程中面临着参数变化范围大、外界干扰复杂的飞行环境,传统的控制方法已经很难满足姿态控制系统的要求.本文将传统的动态滑模和积分滑模综合起来,尝试一种新型的动态积分滑模控制策略律.仿真结果表明,在存在系统参数摄动和外部干扰的情况下,该法很好的消除了抖振,取得较理想的控制效果.

| Abstract: | As it is known that launch vehicle is facing a very harsh environment during the fight process.The challenge of various perturbations and uncertainties has lead to many traditional control methods' failure to meet the requirements of attitude control system.Due to the main advantage of sliding mode control's robustness to the system uncertainties and disturbances in the so-called sliding mode,it has been widely used in engineering.In this paper,regarding particularly on chattering problem,the authors develo... |
