This paper investigates the output feedback control problem of a vehicle platoon with constant time headway (CTH) policy, where each can communicate its consecutive vehicles. Firstly, based on integrated-sliding-mode (ISM) technique, neural adaptive sliding-mode algorithm is developed to ensure that moving CTH policy and full state measurement. Then, further decrease measurement complexity reduce communication load, an protocol proposed only position information, in which higher order...
In this paper, the vehicle platoon control problems for a group of heterogeneous vehicles are investigated, where multiple constraints and communication delays among taken into consideration. A distributed model predictive (DMPC) scheme is proposed to drive desired platoon. DMPC framework, constraints, including state jerk employed describe practical characteristics time-varying bounded. schemes based on techniques. Furthermore, feasibility stability system strictly analyzed. Finally,...
In order to enhance the performance of pure electric vehicle (PEV), dual-energy source storage system, which is composed battery and Ultracapacitor, established. By employing fuzzy logic control theory, energy management strategy presented according requirement for PEV. It can split power between ultracapacitor in a more reasonable way satisfy demands better performance. The result shows that system with optimal effective than threshold reducing current battery, enhancing start-up...
We investigate the vehicle platoon problems, where actuator saturation and absent velocity measurement are taken into consideration. Firstly, a novel algorithm, smooth function is introduced to deal with sharp corner of input signals, proposed for group vehicles by using consensus theory. Secondly, applying an auxiliary system followers estimate velocities, control strategy designed via adaptive approach. Finally, numerical simulations provided illustrate effectiveness approaches.
Due to the limited bandwidth and transmission congestion of vehicle platoon's communication, it is inevitable induce time delay, which significantly degrades control performance platoon, even resulting in instability. This paper focuses on analyzing internal stability under generic communication topologies presents a method computing exact delay margin (ETDM). The proposed can offer necessary sufficient condition with no conservatism. Firstly, reduce analytical complexity computational...

Then, coupled mode surface designed link inter-connected vehicles an method adopted identify estimate variations coefficients. After that, algorithm for with proposed, realizes stable presence...
This paper presents a bio-inspired search behavior model for navigating using geomagnetic information in unknown environments. A multi-objective navigation framework combining random walk movement and stress evolution algorithm is applied to the navigation. Firstly, motivated by animal behavior, we generalize process as convergence of multi-parameter from present point values object values. Then, adopt represent moving vehicle. In addition, used obtain appropriate direction, which realizes...

This paper investigates the vehicle platoon control problems with both velocity constraints and input saturation. Firstly, radial basis function neural networks (RBF NNs) are employed to approximate unknown driving resistance of a vehicle’s dynamic model. Then, bidirectional topology, where vehicles can only communicate their direct preceding following neighbors, is used depict relationship among in platoon. On this basis, adaptive sliding‐mode algorithm an anti‐windup compensation technique...
