METHOD FOR DESIGNING THREE-DIMENSIONAL TRAJECTORY OF UNMANNED AERIAL VEHICLE BASED ON WIRELESS POWER TRANSFER NETWORK

The invention discloses a method for designing a three-dimensional trajectory of an unmanned aerial vehicle based on a wireless power transfer network. The method comprises the following steps: establishing a downlink channel model of the wireless power transfer network; establishing a mathematical model based on maximizing energy harvested by a user, comprising three-dimensional position deployment of an unmanned aerial vehicle, allocation of a charging time, and generation of an energy beam pattern; jointly optimizing on design and analysis of low-complexity iterative algorithms for three-dimensional position deployment of the unmanned aerial vehicle, the charging time and an energy beam; and using branch and bound method to design a three-dimensional flight trajectory of the unmanned aerial vehicle.
