A path planning algorithm for AUV docking operations in tidal current disturbances is proposed, composed of a way-point generator, an optimal planner, and a tidal current estimator. The algorithm adapts the trajectory of the AUV based on tidal current disturbance speed estimation, reducing actuator power consumption while satisfying specifications and limiting power consumption in simulation scenarios.
A path planning algorithm for an Autonomous Underwater Vehicle (AUV) performing docking operations in the presence of tidal current disturbances is presented. The path planner is composed a way-point generator (WPG), an Model Predictive Control based optimal planner (OP), and a tidal current estimator (TCE). The WPG defines the next way-point with respect to the vehicle position and the OP iteratively generates the trajectory over a prescribed future horizon whilst satisfying certain physical and logical constraints. The TCE estimates the tidal current disturbance speed enabling to adapt the AUV trajectory for reducing actuators power consumption. The proposed path planning policy has been evaluated in a set of simulation scenarios to illustrate the ability of the policy to drive the AUV by satisfying specifications and limiting power consumption.
