摘要
针对倾斜转弯导弹自动驾驶仪的设计,提出了一种基于干扰观测器的自适应控制方案。在不考虑气动参数时变的条件下,干扰观测器曾被应用于设计倾斜转弯导弹的自动驾驶仪。但是,当存在严重干扰的情况下,这种基于干扰观测器的自动驾驶仪控制性能会受到影响。为了提高倾斜转弯导弹的鲁棒性和抗干扰性能,提出了一种自适应干扰观测器,其名义模型随气动参数的变化实时更新。最后给出的仿真表明所提出的自适应控制方法可以有效提升倾斜转弯导弹自动驾驶仪的控制性能。
An adaptive control scheme based on disturbance observer was proposed for the bank-to-turn missile autopilot design. The disturbance observer had been previously introduced for bank-to-turn missile system without considering the lfuctuation of the aerodynamic parameters, and the disturbance estimation performance would degrade in the presence of severe disturbances. In order to improve the robustness and anti-disturbance ability of BTT missiles, an adaptive disturbance observer was proposed, the nominal model of the disturbance observer was updated over time along with the aerodynamic parameters. At the last, simulation comparisons show the effectiveness of the proposed adaptive control method.
