Abstract:This paper investigates a cooperative path following problem of multiple unmanned underwater vehicles (UUVs) with complex tracking paths, three-dimensional spatial motion, dynamic changes of model parameters, and wind, wave and current perturbations. Firstly, considering the complexity of tracking paths, an adaptive look forward distance strategy is designed to enable UUVs to better track complex paths. Secondly, for multiple UUVs moving in three-dimensional space, a line of sight guidance law and a cooperative control law are designed to guide the UUVs to move along the parameterised paths in three-dimensional space. Thirdly, for the UUVs under the influence of dynamic changes in model parameters and disturbances such as wind, waves, and currents, an anti-disturbance controller is designed to achieve a unified estimation of dynamic model variations, total disturbance information, and velocity information, ensuring the stability of dynamic control. Simulation results confirm the effectiveness of the proposed three-dimensional cooperative path following control method for UUVs based on adaptive line of sight guidance.
