| 摘 要： | 针对未知有界外部干扰下水下机械手的轨迹跟踪问题，提出了一种分数阶积分滑模控制方法。该方法采用了基于分数阶积分滑模面的指数趋近律，考虑外部扰动，在模型中添加了外部扰动的近似估计项，使得系统可以实现快速收敛，且具有较强的抗干扰能力。利用李雅普诺夫理论证明了该方法的稳定性。对六自由度水下机械手的跟踪问题进行了仿真，结果表明，该控制方法具有良好的轨迹跟踪能力，且对外部干扰表现出良好的鲁棒性。

| Abstract: | A fractional integral sliding mode control scheme was proposed to solve the trajectory tracking problems of underwater manipulators with unknown and bounded external disturbances. The proposed method was made with the adoption of the exponential reaching law that was based on a fractional integral sliding mode surface and with one term added as the approximate estimate for the external disturbances, which made it possible to achieve fast convergence and have strong capacity of resisting disturbances for the systems. Moreover, the stability of the closed-loop system could be guaranteed by the Lyapunov theory. Numerical simulations of the six degree-of-freedom (DOF) underwater manipulators shows promising results that validate the high-precision tracking performance and the better robustness of the proposed control systems against external disturbances. |
