In this paper, a robust model-based battery state of charge (SOC) estimating algorithm is proposed with a novel approach based on multi-models data fusion technique and particle filter (PF). The proposed method is particularly adapted for SOC estimation under conditions of sharp current variations and presence of measurement noise. In this innovative approach, multiple battery models have been used...
Battery state of charge (SOC) estimation is a key issue in battery management system (BMS) for ensuring reliable operation of electric vehicles (EV). This paper proposes a novel SOC estimation method based on iterated extended Kalman particle filter (IEKPF), the main characteristics of IEKPF are to generate the proposal distribution, an accurate approximation of the posterior probability density can...
Many previous studies have shown that traditional TCP slow-start algorithm suffers performance degradation in high-speed and long-delay networks. This paper presents a sender-side enhancement, which makes use of TCP Vegas congestion-detecting scheme to monitor the router queue, and accordingly refines slow-start window evolution by introducing a two-phase approach to probe bandwidth more efficiently...
Solution of the problem of fault accommodation in nonlinear dynamic systems is related to constructing the control law which provides full decoupling with respect to fault effects. Existing conditions are formulated and calculating relations are given for the control law.
In this paper, toll collection data in Guang Dong province are investigated. After pre-processing data, we obtain spatial characteristics and temporal characteristics of OD-Matrix, and further we take insight into the travel times among different vehicle types. The results obtained in this paper extend the corresponding results given in previous works. The study is very important to traffic management...
As the extension of the least significant bits (LSB) steganographic algorithm, steganographic algorithm embedding in two least-significant bits (Two-LSBs for short) has some characteristics, such as visual imperceptibility, higher capacity and easy realization. A new steganalysis method is introduced to detect the existence of hidden message that are randomly embedded in LSB and the second significant...
In this paper, an improved adaptive fault estimation algorithm is proposed for a class of polytopic linear parameter varying (LPV) systems. The conventional adaptive fault estimation design method suffers from low performance of the fault estimation and a strict equation constrain, so a novel fast adaptive fault estimation (FAFE) design method proposed in this paper not only enhances the performance...
