This paper surveys the recent advances in marine mechatronic systems from a control perspective. The survey is by no means exhaustive, but introduces some notable results area. New developments terms of system designs for surface vessels, underwater robotic vehicles, profiling floats, gliders, wave energy converters, and offshore wind turbines are briefly reviewed. In addition, few avenues future research identified.
This article presents an up-to-date tutorial review of nonlinear Bayesian estimation. State estimation for systems has been a challenge encountered in wide range engineering fields, attracting decades research effort. To date, one the most promising and popular approaches is to view address problem from probabilistic perspective, which enables unknown state variables by tracking their distribution or statistics (e.g., mean covariance) conditioned on system's measurement data. offers...
