摘要:

实现稳定且精确的轨迹跟踪是水空两栖航行器(HAUV)实现跨介质运动操作的前提。为解决同轴HAUV在面临建模不确定性和外界环境复杂干扰的水空跨介质轨迹跟踪控制问题,一种非线性扰动观测器(NDO)增强的自适应反步控制器(ABSC)被设计出来。对同轴HAUV的介质跨越机理进行分析,充分考虑了如水体、风浪流等带来的附加变量,通过设计光滑的过渡函数建立了连续的动力学模型。在反步控制器(BSC)构成的控制器基础框架上,通过集成NDO来估计难以测量的集总不确定性,并引入自适应算法补偿NDO的观测误差。自适应算法和NDO联合作用,共同提高了系统鲁棒性。通过李雅普诺夫理论证明了闭环系统稳定性。仿真结果表明,本文所设计的控制器对未知扰动具有较强抑制能力,能够实现对水-空跨越轨迹的有效跟踪。

Abstract:

The stable and accurate trajectory tracking is a prerequisite for Hybrid Aerial Underwater Vehicle (HAUV) to achieve trans-media motion operation. To address the trajectory tracking control problem of coaxial HAUV in water-air cross-medium environments, which faces modeling uncertainty and complex interference, a Nonlinear Disturbance Observer (NDO) enhanced Adaptive Backstepping Controller (ABSC) is designed. The cross-domain mechanism of coaxial HAUV is analyzed, the additional variables such as water, wind and wave are fully considered, and a continuous cross-media dynamic model is established by using smooth and continuous transition function design. Based on the basic framework of Backstepping Controller(BSC), the integrated NDO is used to estimate lumped uncertainty which is difficult to measure, and an adaptive algorithm is introduced to compensate the observation error of NDO. The combination of adaptive algorithm and NDO improves the robustness of the system. The stability of the closed loop system is proved by Lyapunov theory. The simulation results show that the controller designed in this paper has a strong ability to suppress the unknown disturbance and can effectively track the water-air cross-domain trajectory.
