Input Flow Control Algorithms of the Trasnsport System

This article is analyzed the flow control algorithms for a conveyor system with an input accumulating bunker. For control the flow parameters of the conveyor section, the output flow is controlled by the filling of accumulating bunker, which is located on the input of the conveyor section. For the design of control algorithms, a dynamically distributed dimensionless conveyor model (PiKh-model) was used. The quality control criterion requires the minimum deviation of the output flow of the conveyor section from the planned value. The initial movement time of the conveyor line during which the output flow value is independent of control is determined. The output value material flow from a conveyor during the start period is determined by the value of the linear density of the material on the conveyor at the start of the conveyor line. When designing optimal control algorithms, limitations on the maximum value of the accumulating bunker capacity and control restrictions are taken into account. Optimal control algorithms are considered for variants with unlimited and limited accumulating bunker capacity. The synthesis of optimal controls for the limit values of controls of the material flow from the bunker has been performed.
