外文摘要：In this paper, a new global fast adaptive terminal sliding mode control method is proposed for the nonlinear and strong coupling characteristics of the multi-motor synchronous control system of the four-leg offshore platform. Based on sliding mode control, an adaptation control law is introduced to adjust the controller parameters in real-time, which effectively reduces the oscillation problem of traditional sliding mode control. At the same time, the introduction of the fast factor and the global sliding factor makes the multi-motor system capable of being Stable quickly, while ensuring that the system has good global rapid convergence and stability when subjected to external interference. Finally, the steady-state performance of the multi-motor synchronous system is analyzed by Lyapunov stability, and the effectiveness of this method is verified by simulation experiments. ? 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
