基于收缩理论的高超声速飞行器控制
Contraction theory-based control for hypersonic vehicle
摘要
Abstract
In order to track a predetermined instruction for the hypersonic vehicle,a control method was proposed for its strict feedback model based on the theory of contraction.Due to the relative independence of attitude and speed subsystems,controllers was designed separately.During the design process,on the basis of the contraction theory,adaptive control was adopted to identify the model uncertainty online.Moreover,the contraction-based singular perturbation analysis is used to reduce the subsystem dynamics.By analyzing the contraction-based robustness of the hierarchical interconnection of the subsystems,it can be proved that the differences of the state errors between the original and the reduced subsystems and the differences of the filters are explicitly bounded.With this method introduced,the total system state of the hypersonic vehicle can converge to a ball centered about the desired trajectory semiglobally.关键词
