A Circular-Arc-Type Magnetic Coupler with Strong Misalignment Tolerance for AUV Wireless Charging System

چکیده
The wireless charging system (WCS) is widely employed to solve the problem of underwater autonomous vehicles (AUVs). However, AUV prone misalignment caused by tidal currents, which directly leads fluctuations in transmission efficiency and output power. For this reason, a circular-arc-type (CA-type) magnetic coupler with strong tolerance was proposed article. Compared ring-type coupler, had better field convergence lower weight. Further, effect dimensional parameters on CA-type performance analyzed ANSYS Maxwell, were optimized, its coupling coefficient could finally reach 0.671. To analyze influence EE-type UI-type cores are compared. Within same range rotation [−10°, 10°] axial [−30, 30 mm], core has stronger adaptability, it can achieve stable power 575 W DC-DC 92.51% when rotational occurs. A WCS experimental prototype built based one couplers results verify correctness theoretical analysis simulation results.

A Tur'an-type problem for circular arc graphs
A circular arc graph is the intersection graph of a collection of connected arcs on the circle. We solve a Turán-type problem for circular arc graphs: for n arcs, if m and M are the minimum and maximum number of arcs that contain a common point, what is the maximum number of edges the circular arc graph can contain? We establish a sharp bound and produce a maximal construction. For a fixed m, t...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

متن کاملAn Autonomous Coil Alignment System for the Dynamic Wireless Charging of Electric Vehicles to Minimize Lateral Misalignment
This paper proposes an autonomous coil alignment system (ACAS) for electric vehicles (EVs) with dynamic wireless charging (DWC) to mitigate the reduction in received power caused by lateral misalignment between the source and load coils. The key component of the ACAS is a novel sensor coil design, which can detect the load coil’s left or right position relative to the source coil by observing t...

In this paper, we present an ef®cient sub-optimal algorithm for ®tting smooth planar parametric curves by G 1 arc splines. To ®t a parametric curve by an arc spline within a prescribed tolerance, we ®rst sample a set of points and tangents on the curve adaptively as well as with enough density, so that an interpolation biarc spline curve can be with any desired high accuracy. Then, we construct...
