In response to the short endurance time of unmanned aerial vehicles(UAVs)operating in the sea area and the dynamic movement of charging platforms that are susceptible to disturbance,a self-stabilized wireless charging system for ship-borne UAVs has been designed.The system uses the STM32 microcontroller as the main control core,including the Stewart self-stabilized platform and wireless char-ging round table on the carrier side,the power monitoring module on the UAV side,and the monitoring host computer on the PC side.The platform attitude data and battery power data are processed by Kalman filtering algorithm.Through testing,the Stewart platform can achieve stability of the wireless charging round table platform under certain levels of disturbance.The wireless charging round table can meet the wireless charging requirements of UAVs,while the host computer can receive real-time power data from UAVs and monitor the entire charging process in real time.
