For automatic speed control shaft of the screw device additional system is used to serving control the frequency of rotation of the shaft dispenser. The shaft drive auger dispenser motor is adjusta-ble. The purpose of the work is the development and research of system of the serving shaft speed screw facility materials. For modelling the serving control of the rotational speed of the shaft screw dispenser material was used the program ‘Matlab*Simulink’. In the study a potentiometer, a mathematical model which is written in the form of aperiodic link of the first order with a transfer func-tion were used. In the simulation system, the serv-ing, the shaft speed was determined by the effect of the controller on the dynamics of the transients of the system with sequential switching off compo-nents: proportional P, integral I, and a differential D. the results of the transient studies have shown that when using analog proportional controller transient oscillatory is with amplitude of 2 mm. The propor-tional component is the basis of the regulatory im-pact. The use of PI regulator has allowed reducing the amplitude of 1.9 mm. Control process with PID controller provides the amplitude of 1.4 mm.
