Abstract: The paper considers the operation of a conveyor belt with two drive drums. To create a mathematical model of the conveyor, the entire track was divided into eight concentrated masses. The electric drive of the drive drums consists of an asynchronous motor and a frequency converter for each drum. The speed controller is located in the setting channel of the first drive drum. To obtain speed feedback, the speed sensor is mounted on the loaded part of the belt in the center of the concentrated mass, the first after the drive drum. Several ways of calculating the conveyor speed controller are considered. The first option is to calculate the simplified transfer function of the conveyor, for the synthesis of the regulator, the transfer function of the eighth concentrated mass simplified to the second degree in the denominator is used. The second option is to calculate from the obtained analytical dependence of the parameters of the transfer function of the concentrated mass of the conveyor on the belt parameters (stiffness, viscosity, mass), which allows synthesizing a control system without creating a mathematical model. To check the operation of the regulator with coefficients calculated using the second method, the start-up of both a fully and partially loaded conveyor was considered. The quality of the transient process was investigated for both variants of the regulator coefficients. The simulation was performed in the SimInTech mathematical modeling environment. The simulation results show the applicability of both considered methods for the synthesis of a conveyor speed controller.
