Abstract
Underwater optical wireless communication (UOWC) technologies are essential for the growth of future underwater communication applications. As the demand for capacity increases, UOWC is considered an emerging alternative technology in the underwater communication area. However, maintaining a controlled line-of-sight link between transmitter and receiver is a significant challenge because the alignment angle required for trajectory tracking control is not directly measured and has to be estimated. In this talk, I will present our recent works on estimating the alignment angle between autonomous underwater vehicles. Specifically, I will discuss a novel estimation-based trajectory control algorithm for a light-emitting-diode (LED)-based optical communication model. Then, I will discuss localization and tracking control of a mobile target ship with an autonomous underwater vehicle (AUV) in the underwater environment. The framework uses a hybrid acoustic-optical underwater communication to drive the AUV to the maximum achievable data rate angle. The acoustic link is used for the non-line-of-sight localization, and the optical link is for the line-of-sight transmission. I will conclude the talk by providing a perspective on the potential impact of designing distributed cooperative control systems for exploring seafloor and monitoring underwater engineering applications.
