Purpose. Investigation of transients in the control system of continuous dosing equipment for bulk materials using PI and PID regulators and evaluation of their impact on the quality of work elements.
Method. Using the Mathlab: Simulink software environment to develop a mathematical model, conduct experimental research and assess the impact on the working bodies of the control system of continuous dosing equipment.
Researchresults. Control of motor parameters (motor characteristics) by means of standard regulators of their comparison of advantages and disadvantages. described in many standards and scientific papers. However, modeling the engine operation process in dosing systems is significantly complicated due to the inertness and adhesion of bulk material dosed in the core of the hopper, it can significantly affect the final result of the finished mixture. continuous operation equipment using PI and PID controllers, an experiment was performed on a mathematical model using PI and PID controllers to assess their impact on the control system of the plate feeder continuous action. The results of the simulation can be used to decide on the type of controller control of transient characteristics of the engine, at development of control system of plate feeders in mixing complexes of continuous action.
Scientificnovelty. Scientific novelty. The parameters influencing the frequency with which the motor of the plate feeder of continuous action rotates are determined. The time of the transient process of engine operation and the value of the maximum dynamic deviation are determined. The expediency of using regulators of one or another type for certain modes of operation of feeders is proved.
Practical significance. The obtained results will reduce the transient time in the operation of the feeder motor and increase the operating time until the failure of the entire system. Design changes are proposed that will reduce the amount of ripple and improve the performance of continuous dosing equipment.
