The paper deals with the problem of synthesis of a conveyor belt speed control system in order to minimize the fluctuations of the belt sections during the start of the conveyor. To calculate the coefficients of the control system regulators, it is necessary to obtain the transfer function of the control object. Various ways of constructing a mathematical model of the conveyor are considered. The construction of a mathematical model of the conveyor as a system with concentrated parameters using computer modeling tools makes it possible to obtain transfer functions of the output parameters of the conveyor. When the conveyor is divided into five concentrated masses, the transfer functions have up to the eighth order of the Laplace operator in the denominator, which complicates the synthesis of the control system. To simplify the transfer function to the second order, various ways of simplification are considered, the authors propose to use the method of reducing closely spaced zeros and poles. This makes it possible to simplify the transfer function to the second order without using a complex mathematical apparatus, which allows using classical methods in the synthesis of the control system. The study of starting the conveyor without a control system and with a control system has shown the effectiveness of this method of simplifying transfer functions. The use of the control system made it possible to reduce the vibrations of the tape from 11% to 4% and reduce the transition time from 30.2 seconds to 21.6.
