Magnetically Coupled Resonant Wireless Power Transfer(MCR-WPT)technology has the advantages of high transmission power and high efficiency over a transmission distance of tens of centimeters.Therefore,certain research and applications have been obtained in the fields of electric vehicle wireless charging,human implantable medical devices,and consumer electronics products.Most of the current research and engineering practices on MCR-WPT technology Wireless energy transmitting and receiving devices are usually at rest,there are relatively few literature reports on wireless energy transmission when both of them are in the process of movement.Firstly,the article analyzes the different ways and characteristics of wireless energy transmission,and summarizes the current research status of MCR-WPT technology application at home and abroad.Then use circuit theory to derive the relationship between the energy transmission efficiency of the MCR-WPT system and the system parameters Then establish a theoretical calculation model according to the vertical distance change,horizontal offset,and angle deflection of the coupling mechanism between the transmitting and receiving coil under the motion state.Analyze the mutual inductance of the coupled resonant coil under the position shift state.Study its impact on system energy transmission efficiency,provide theoretical guidance for system scheme design.Then establish the simulation model of the position offset of the coupled resonant coil,simulation analysis of the impact of position offset on system transmission efficiency,providing data reference for dynamic tracking wireless energy supply experiment.Secondly,in the multi-physics electromagnetic simulation software construct the field-circuit joint analysis model,and analyze the influence of each parameter in the coupling mechanism and system by using the controlled variable method,and optimize the MCR-WPT system parameters and the structure of the coupling resonant coil.The 2ASK modulation and demodulation technology is used to realize the design of the SWIPT module.Proportional control algorithm is used to complete the magnetic stripe tracking algorithm design of the energy supply vehicle.Finally,the MCR-WPT system experiment platform was built,and the wireless energy transmission experiment of the coupled resonant coil position offset state was carried out to verify the theory and simulation analysis results,and summarize the relevant conclusions.On this basis,an experimental platform for dynamic tracking wireless energy supply system was built,which realized the position tracking of the energy supply vehicle by the energy receiving vehicle and the dynamic wireless energy supply to the energy receiving target.By detecting the changes in the electrical parameters of the transmitting end,the relative position offset of the supply and receiving vehicle is calculated,and the automatic correction offset control algorithm of the two vehicles is designed,which verifies the feasibility of applying the system to the pipeline robot dynamic real-time energy supply...
