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

There is an issue of the fish adhering to the metal grids of grill strongly after grilling fish.Recently, the temperature in a grill equipment is over 500 °C, Fluorine resin coating which has low adhesion property can not endurant at 500 °C.In order to overcome this issue, verona wig we proposed a new grill not to adhere a fish with Ultra-H
