Abstract: The article focuses on developing wireless charging systems for autonomous floating vehicles. The difficulty of operation in marine conditions arises from the instability in the relative positions of the transmitting and receiving coils due to oscillatory motion. To ensure stable charging, it is necessary to dynamically estimate system parameters, primarily mutual inductance. A review of algorithms for estimating mutual inductance found that they do not consider the marine conditions. This work aims to develop an experimental setup for studying dynamic estimation algorithms in wireless charging systems under oscillatory motion. The theoretical section presents a mathematical model expressed through differential equations, and outlines a design of experiments, which includes a series of measurements. These measurements are carried out under oscillatory motion imitating roll, pitch, and heave, and under different distances between the coils and the battery charge levels. Measurements of currents and voltages are carried out at high frequency and synchronously with the measurement of the coil displacement coordinates. The analysis showed that the experimental setup mechanism should have two degrees of freedom. A 150 W wireless charging system has been developed, with a mutual inductance variation range of up to $34 \mu \mathrm{H}$. The design of the experimental setup allows for the study of strong and weak magnetic coupling modes with changes in distance and rolling angle. The results will be useful for selecting and tuning estimation algorithms, as well as for controlling wireless charging systems in marine environments.
