Accurately estimating the state of charge (SOC) of the battery is the basis of battery management system. Based on a linear equivalent circuit model, this paper has introduced a switched battery model to model the complicated physical and chemical reactions properties. The SOC is determined by the battery electromotive force at a present battery state that is estimated through the $H_\infty$ switched...
According to the large continuous annealing furnace widely used to produce ductile iron pipes in metallurgy area, heat transfer mathematical model was built in the paper. Based on the pipe setting temperature curve and boundary conditions, temperature distribution in the furnace is deduced by solving heat transfer differential equation. The aim is to optimize the control temperature curve. In order...
On the basis of the mathematical model, the equations have been derived. They are simulated by VB program language. The residence time and the position of a particle at any moment can be defined according to rotational speed of the rotary dryer, radius of the drum, the slope of the drum, wind-force and the particle quality. Simulated results are satisfactory.
In the paper, extended-circular flights characteristics of rotary dryers is researched. On the basis of the mathematical model, a set of equations has been derived to calculate the solids holdup on extended-circular flights in such dryers. The solids holdup and its ratio to the maximum are explored. A kind of practical rotary dryer is simulated by VB program language. The simulated results, obtained...
In the paper, a Simulation method of complex repairable system based on Stateflow is put forth. At first, the concepts of complex repairable system and Stateflow are introduced. Then, the analyzing concept, procedure, solution to difficult problems and statistics model of establishing complex repairable system model based Stateflow is put forth according to finite state-machine theory and object-oriented...
