摘 要: 由优化滑块参数和控制律设计两方面入手研究变质心飞行器控制问题。为降低伺服回路对飞行器姿态运动的影响,通过动力学分析给出变质心飞行器一种布局形式;以此为基础建立仿射型控制模型,分析不确定因素;最后基于名义模型设计模糊滑模控制律,考虑滑块导轨的不确定性,给出鲁棒自适应补偿项。仿真结果验证了算法的有效性。
关 键 词: 飞行器设计;变质心控制;再入飞行器;滑模控制;自适应

Abstract: In this paper, both optimization of moving mass parameters and control law design are considered to control a moving mass vehicle. In order to reduce the influence of the servo loop on the attitude of the vehicle, a layout of the moving mass vehicle is given through dynamics analysis; taking the layout as a base, an affine control model is derived, and uncertain factors are analyzed; finally, a fuzzy sliding mode control law is proposed, and a robust adaptive compensate is given based on the uncertain of the moving mass track. Simulation results demonstrate that the algorithm is effective.
Key words: aircraft design; moving massed control; reentry vehicle; sliding mode control; self adaptive
