研究了非最小相位欠驱动高超声速飞行器的二阶动态滑模控制问题。首先，介绍了欠驱动高超声速飞行器姿态控制模型。讨论了车辆的规范形和非最小相位性质。利用系统分解方法将非最小相位系统分解为最小相位子系统和非最小相位子系统。其次，开发了SODSMC方案。针对这两个子系统分别设计了常规滑模控制器和二阶动态滑模控制器。此外，还给出了非最小相位子系统的动态滑动流形。对非最小相位欠驱动高超声速飞行器的仿真结果验证了所提出控制方案的有效性和鲁棒性。
This paper deals with the second-order dynamic sliding-mode control (SODSMC) problem for nonminimum phase underactuated hypersonic vehicles. First, the underactuated hypersonic vehicle attitude control model is introduced. The normal form and the nonminimum phase nature for the vehicle are discussed. Thus, the nonminimum phase system is divided into the minimum phase subsystem and the nonminimum phase subsystem via the system decomposition approach. Second, the SODSMC scheme is developed. The conventional sliding-mode controller and the second-order dynamic sliding-mode controller are designed for the two subsystems. Besides, the dynamic sliding manifold is provided for the nonminimum phase subsystem. Simulation results for the nonminimum phase underactuated hypersonic vehicle are presented to demonstrate the effectiveness and robustness of the proposed control scheme.
