Accurate state-of-charge (SOC) estimation is essential to battery management system. The widely adopted estimation methods based on Kalman Filter (KF) fail to take the variable environmental conditions into consideration, which may result in a poor accuracy. This paper proposes a novel estimation model based on KF method to estimate SOC of Lithium-ion battery. In the proposed model, the noise variances...
A set of Boussinesq equations for simulating internal waves propagating in a two-fluid system in the presence of parallel currents is theoretically derived in this paper.

This paper performs a preliminary examination for higher-order modified Boussinesq equations for internal waves propagating between a two-fluid system bounded by two rigid walls. A set of three equations constitutes the new equations in which two dpeth parameters denoting two arbitrary elevations make the model flexible. To acquire the optimal model, the technique of Padé approximation is used to...
In actual industry systems, some input/output variables of the control and optimization models may be not crisp instead of interval-valued. This paper proposes a new Extreme Learning Machine based on interval-value(I-ELM). The model is composed of two parts, one is an ordinary ELM for modelling the midpoint of the interval-valued data, the other is a modified ELM for modelling the width of the interval-valued...
I put forward a new interpolation called Adams-Bashforth interpolation of NURBS (Non-Uniform Rational B-Splines) curve in order to realize higher precision under the condition of satisfying the speed demand. IN this method, I calculated next parameter point by Adams-Bashforth equation and I used difference equation instead of derivation. I simplified and approximated the interpolation algorithm so...
