Design and experimental validation of event-triggered multi-vehicle cooperation in conflicting scenarios Research Article

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 11,   Pages 1700-1713 doi: 10.1631/FITEE.2100504

Abstract:

Platoon control is widely studied for coordinating (CAVs) on highways due to its potential for improving traffic throughput and road safety. Inspired by platoon control, the cooperation of multiple CAVs in can be greatly simplified by virtual platooning. Vehicle-to-vehicle communication is an essential ingredient in virtual platoon systems. Massive data transmission with limited communication resPreprintources incurs inevitable imperfections such as transmission delay and dropped packets. As a result, unnecessary transmission needs to be avoided to establish a reliable wireless network. To this end, an event-triggered robust control method is developed to reduce the use of communication resources while ensuring the stability of the virtual platoon system with time-varying uncertainty. The uniform boundedness, uniform ultimate boundedness, and string stability of the closed-loop system are analytically proved. As for the triggering condition, the uncertainty of the boundary information is considered, so that the threshold can be estimated more reasonably. Simulation and experimental results verify that the proposed method can greatly reduce data transmission while creating multi-vehicle cooperation. The threshold affects the tracking ability and communication burden, and hence an optimization framework for choosing the threshold is worth exploring in future research.

Target height and multipath attenuation joint estimation with complex scenarios for very high frequency Research Articles

Sheng CHEN, Yongbo ZHAO, Yili HU, Chenghu CAO, Xiaojiao PANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 937-949 doi: 10.1631/FITEE.2100003

Abstract:

for is a difficult problem due to the in the radar field, especially in where the reflection condition is unknown. To deal with this problem, we propose an algorithm of target height and multipath attenuation joint estimation. The amplitude of the surface reflection coefficient is estimated by the characteristic of the data itself, and it is assumed that there is no reflected signal when the amplitude is very small. The phase of the surface reflection coefficient and the phase difference between the direct and reflected signals are searched as the same part, and this represents the multipath phase attenuation. The Cramer-Rao bound of the proposed algorithm is also derived. Finally, computer simulations and real data processing results show that the proposed algorithm has good estimation performance under and works well with only one snapshot.
