Supervisory switching control of an unmanned surface vehicle [PDF]

open access: yesOCEANS 2015 - MTS/IEEE Washington, 2015
A novel method to determine the switching of controllers to increase the performance of a system is presented. Three controllers are utilized to capture three behaviors representative of unmanned surface vehicles (USVs). An underactuated nonlinear controller is derived to transit the vehicle between locations; a fully-actuated nonlinear controller is ...
