Mapping bathymetric and hydrographic features of Glover’s Reef, Belize, with a REMUS autonomous underwater vehicle
We used an autonomous underwater vehicle (AUV) to survey bathymetry and water mass properties at Glover’s Reef atoll in Belize as part of a multidisciplinary study of population connectivity of Nassau grouper (Epinephelus striatus). Nassau grouper populations are declining dramatically throughout its range in the Caribbean because of overfishing. In response, Marine Protected Areas have been es...
متن کاملPhosphorus-rich waters at Glovers Reef, Belize?
Coral reefs worldwide are experiencing increasing anthropogenic impacts on local, regional and global scales. Two major human impacts––nutrient enrichment and overfishing––were recently assessed by McClanahan et al. (2002) at Glovers Reef, an atoll offshore the Belize Barrier Reef in the western Caribbean Sea. The most significant finding from this experimental study was the dramatic effect of ...
متن کاملOPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE
In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
متن کاملPerformance Analysis: Pid and Lqr Controller for Remus Autonomous Underwater Vehicle (auv) Model
Autonomous underwater vehicles (AUV) are used in many applications like mining, aquaculture and military applications. AUV is highly nonlinear system; modeling and controller performance is challenging issue for the researchers. In this paper a linear quadratic regulator (LQR) and proportional integral derivative (PID) controllers are designed for the depth control system of AUV. These controll...
متن کاملObstacle Avoidance While Bottom Following for the REMUS Autonomous Underwater Vehicle
Future Naval operations necessitate the incorporation of autonomous underwater vehicles into a collaborative network. In future complex missions, a forward look capability will also be required to map and avoid obstacles such as sunken ships and reefs. Following previous work on steering control, this work examines collision avoidance behaviors in bottom following using a hypothetical forward-l...
