EVENT TRIGGERED PRESCRIBED TIME TRAJECTORY TRACKING CONTROL FOR UNMANNED SURFACE VESSELS WITH LUMPED DISTURBANCES AND PRESCRIBED PERFORMANCE CONSTRAINTS

Abstract This article proposes a prescribed-time trajectory tracking control algorithm for unmanned surface vessels with lumped disturbances, limited communication, and error constraints, utilizing an event-triggered mechanism.Firstly, we present a prescribed-time lumped disturbances observer to accurately estimate the lumped disturbances, includin
