SIMULATION OF THE CONVEYOR SPEED STEP CONTROL

Abstract

The possibilities of step control conveyor speed simulation within Mathcad and Simulink software are considered in the article.. General statistical parameters of the conveyor load can be used for a rough estimation of the speed step values only. To check
the efficiency of the control algorithms and to determine the characteristics of the control system more accurately it is necessary to simulate the process of speed control with real values of traffic for a work shift or for a day. The analytical formulas for optimal speed step values were obtained using empirical values of load. The simulation example within
Mathcad software is considered. The values of Vср and Nп for two-step, three-step and four-step control regimes were calculated with linear interpolation of 104 load data and the use of Mathcad programming operators. Work results can be applied during the design of belt conveyors with adjustable drives.
