In a multiple excitation unit wireless power transfer system, power control flexibility is a critical feature. To develop a system with environmental sensing capability and a smart power distribution strategy, a cooperative control method is proposed for the excitation units. A multiple coupling coefficient identification method was developed by utilizing the DC information of each excitation unit. Furthermore, a bi-operation mode with adaptive area division is proposed to achieve maximum efficiency in the optimum coupling area and to satisfy the fundamental power requirement for a weak coupling area. In the identification and control implementation process, this method is easy to implement and the response speed can be guaranteed because only the DC input current and the duty cycle of the DC regulator information are required. In addition, the proposed approach was evaluated based on experimental analysis.

“…Moreover, if the insertion loss owing to the conductor loss or substrate loss of the MTM slab can be reduced, it will provide great potentials to improve the PTE of the WPT systems. Wang et al [38] have demonstrated the superconductor based MTM slab with low conductor loss. It is shown that the lower loss properties of the superconductor incorporated with the properties of MTMs can improve more the PTE of the WPT systems effectively.…”

With the recent advancement and progress in the field of wireless power transfer (WPT), there is an ever increasing demand for high power transfer efficiency (PTE) of the WPT systems and improved transfer distance for the end-users. However, some existing WPT systems have limited PTE and transfer distance as they take the inductive coupling approach, where the PTE dramatically decreases as the distance between (Tx) and receiver (Rx) coils increases. Alternatively, magnetic resonance coupling (MRC) is used as a mid-range WPT approach, for which the insertion of metamaterials (MTMs) between Tx and Rx coils is exploited to improve efficiency. MTMs are artificially engineered materials that show uncommon electromagnetic properties, such as evanescent wave amplification and negative refractive characteristics, which could be utilized for the enhancement of PTE. In this paper, a comprehensive review on recent progresses in the MTM-based WPT systems is reported, where previously reported MTM-based WPT systems are compared in terms of various parameters such as configurations, operating frequencies, dimensions and PTE. Also, the PTEs of these systems were plotted as a function of the normalized transfer distance. This review is expected to provide an insight for understanding the trends of the MTM-based WPT systems and serve as a reference for researchers who work on WPT systems and their applications.

“…In SUMO, the following model is used to simulate the moving behavior of a vehicle on the road, especially how the vehicle follows the vehicle in front of it. SUMO implements a variety of following models, but the Krauss model [17] is the default following model in SUMO, which calculates the maximum safe speed of the vehicle based on the concept of safe distance. The IDM [18] is a more complex following model, which takes into account the current speed of the vehicle, the distance to the vehicle in front, and the difference in speed between the two vehicles to dynamically adjust the speed of the vehicle.…”

Under the development of intelligent network technology, drivers can obtain the surrounding traffic situation in real time, which is conducive to improving the stability of traffic flow. Therefore, this paper proposes a new curve-car-following model considering multi-vehicle information of adjacent lanes in connected environment, and conducts linear and nonlinear stability analyses of the model to demonstrate the effectiveness of the proposed model and its ability to improve the stability of traffic system; in addition, numerical simulation experiments of traffic flow convoys are designed to analyze the effects of different parameters in the proposed model on the stability of the traffic flow and test the proposed model’s ability to maintain the following behavior in a convoy. Furthermore, numerical simulation experiments are designed to analyze the effects of different parameters in the proposed model on the stability of traffic flow, and to test the ability of the proposed model to maintain the following behavior in the convoy. The model can provide theoretical guidance to alleviate traffic congestion and improve safety, and extend the application of the following model in curved multi-lane road scenarios.
