A navigation strategy for achieving quasi-optimality for autonomous underwater vehicles (AUVs) is presented. The objective of the optimal navigation is the minimum-time transit of an AUV in a flow field of sea current disturbance. Reactive optimal guidance revisions followed by tracking controls are the key features of the proposed quasi-optimal navigation strategy. In this research, a globally working...
Optimal and quasi-optimal navigations of an AUV achieved by the minimum time guidance in undersea area of sea currents are presented. When an AUV is to transfer to a given destination within an area of sea current disturbance, ingenious guidance enables the minimization of navigation time. In this study, a numerical procedure to obtain solution of the optimal guidance law in undersea area of sea current...
