Next generation 5G communication systems will need to employ a range of diverse technologies in order to support vehicle-to-everything (V2X) use cases, ultimately leading to accident-free, cooperative autonomous vehicles that use the available roadway efficiently. V2X is considered as one of the most challenging applications of 5G, as it requires ultra-reliable and low-latency communication for safety-critical...
In this paper, we study the curvature-constrained path planning problem for AUV docking in stationary obstacle environment. Expanded obstacle circles are used to redefine the polygonal obstacles, thus the curvature constraint is incorporated into the path planning algorithm. Unlike the existing algorithms that try to avoid the obstacles when the planning path collides with them, the novel algorithm...
As applications for autonomous ocean vehicles expand into more dynamic and constrained environments, such as shallow, coastal areas, the benefits of using more precise dynamic model for control and estimation become more compelling. This paper presents a nonlinear observer for current estimation based on AUV dynamic model. Here, AUV dynamic model in currents is taken into consideration. Motivated...
While ocean vehicles often operate in nonuniform currents, the effects of flow gradients on vehicle dynamics are typically ignored in motion models used for control. As applications for autonomous underwater vehicles (AUVs) expand into more constrained, dynamic environments, such as underwater docking, the benefits of using more precise motion models for motion prediction and control become more compelling...
A small-size autonomous underwater vehicle (AUV) for underwater environmental sampling is developed. Example applications include bottom mapping using a sidescan sonar, and thermocline tracking using the conductivity-temperature-depth sensor. The AUV has a modular mechanical, electronic and software design which allows for a simple integration of payload sensors selected for different applications...
It is often crucial in most of today's Autonomous Underwater Vehicles (AUVs) missions that the vehicle position be known precisely. Navigation performance of an Aided Inertial Navigation System (AINS) is always limited by the accuracy of sensors. In this paper we focus on enhancing performance of the AINS via micronavigation, which exploits a so-called Displaced Phase Center Antenna (DPCA) technique...
As Autonomous Underwater Vehicles (AUVs) play an increasingly important role in ocean community, localization of AUVs is attracting more and more attention in various applications. This paper presents a simple iterative solution to passive localization of an AUV which has a periodic sonar transmission. The method exploits the time difference of sonar transmissions and receiving interval measurements...
Based on the study of the different control methods of various hybrid electric vehicles, this paper proposes a control strategy employing power follower and thermostat. This strategy takes the battery SOC value and the engine output torque as the primary controlling factors, compiles its control status flow using Stateflow, and matches parameters of various components of the vehicle according to the...
