無線電力伝送のためのビーム・運動体協調制御の研究

抄録

The present paper is the first report of the experimental study on the energy efficiencies in the millimeter wave power transfer to an autonomously-controlled MAV. A tight beam of millimeter wave at 28GHz was transmitted vertically upward, and a quad-rotor type MAV was autonomously controlled using the Iterative Feedback Tuning method to hover over the beam and receive the millimeter wave power. As a results, it was found that the maxi-mum value of the receiver efficiency was (1±2)x10-3 and its duty ratio was 0.29±0.08, for which the distance be-tween the MAV and the millimeter wave transmitter was 800 mm. The energy loss and the low duty-ratio were both oriented mostly from the loss in the capture efficiency due to the location scattering of the MAV.
