摘要:

针对存在未知气动参数的吸气式高超声速飞行器纵向运动控制问题,提出一种基于不变流形的自适应动态面控制方法.通过合理假设将高超声速飞行器纵向模型分解为弹道倾角回路和速度回路,分别实现对弹道倾角和速度参考指令的跟踪.弹道倾角回路被表达为严反馈形式进行控制器设计.采用基于不变流形的自适应方法实现了对未知参数的估计.所提出的自适应动态面控制方案能保证未知参数估计误差全局一致稳定和闭环系统全局有界稳定,且估计器和控制器设计不存在耦合,因此参数设计更加容易.仿真结果验证了该控制方法在参数估计方面的显著优势和良好的闭环系统性能.

Abstract:

An adaptive dynamic surface control scheme based on invariant manifold was proposed for the longitudinal motion control problem of hypersonic vehicle. With reasonable hypothesis, the longitudinal dynamic model was separated into flight-path angle loop and velocity loop. Flight-path angle loop was formatted into parametric-strict-feedback form. The unknown parameters of the system were estimated based on the method of invariant manifold. The proposed dynamic surface control scheme can guarantee the global uniform stable of the error of estimation and the global boundedness of the closed system. The decoupled relationship between estimator and controller made the parameter tuning more easily than the traditional adaptive dynamic surface method. Simulation results validate the prominent improvement in parameters estimation and the good performance of the closed system.

Key words: hypersonic vehicle, tracking control, adaptive estimate, dynamic surface control, invariant manifold
