Abstract Resonance selectivity is a new way to achieve “Single-input Multi-output” (SIMO) system via wireless electromagnetic power transmission. But it is limited to low power and open loop systems. This paper presents a new method that uses the principle of resonance selectivity of which system is close loop and the power is over 10w. By using this method, we drive three DC motors to control a delta robot which is based on flexible linkages with feedback control. In this paper, we achieve the position control of delta robot through SIMO and wireless control. This paper introduces the principle of wireless control based on magnetic coupling resonance and the details about control system, and the fabrication and analysis of delta robot based on flexible linkages. According to the results of our experiment, we demonstrate that this method can be applied to control delta robot.

Power Transfer Efficiency

In a wireless power transfer (WPT) system, the power transfer efficiency (PTE) decreases sharply with the increase in transfer distance. Metamaterials (MMs) have shown great potential to enhance PTE in mid-range WPT systems. In this paper, we propose two MM slabs of a 3 × 3 array to enhance the magnetic coupling. The MM unit cell was designed by using square spiral patterns on a thin printed circuit board (PCB). Moreover, the asymmetric four-coil WPT system was designed and built based on the practical application scenario of wireless charging for unmanned devices. The simulation and experimental results show that two MM slabs can enhance power transmission capability better than one MM slab. By optimizing the position and spacing of two MM slabs, the PTE was significantly improved at a mid-range distance. The measured PTEs of a system with two MM slabs can reach 72.05%, 64.33% and 49.63% at transfer distances of 80, 100 and 120 cm. When the transfer distance is 100 cm, the PTE of a system with MMs is 33.83% higher than that without MMs. Furthermore, the receiving and load coils were integrated, and the effect of coil offset on PTE was studied.

Purpose The purpose of the paper is to analyze the impact of coupling on the distribution of the magnetic field and study the characteristics of the magnetic flux density in the transmission process of the magnetic coupling resonant wireless power transmission (MCR-WPT) system, which provides guidance on the design of the WPT system. Design/methodology/approach In this study, a finite element simulation analysis was conducted and a three-dimensional (3D) electromagnetic field measurement platform was used. Findings It is shown that the distribution of the magnetic field, as well as the position of maximum magnetic flux density, will change when the coils are coupled. The simulation results of the magnetic field distribution, as well as the transmission performance, are different from those in practice. It cannot describe the actual performance of WPT system. Originality/value A 3D electromagnetic field measurement system and the host computer software are designed to help optimize the simulation and carry out more accurate and efficient research. The 3D electromagnetic field measurement system can be used to study the distribution of the spatial electromagnetic field, influencing factor, exposure and interoperability between different coils.
