Control System for a Discrete Weight Meter

Abstract

The paper deals with the synthesis of a control system for a discrete weight dispenser. To determine the law of regulation, his mathematical model was obtained on the channel “voltage frequency on the stator of the electric motor of the feeder - the reading of the material mass sensor”, which was subsequently linearized, which allowed, by the method of assigning poles, to synthesize the analog regulation system. The synthesized control algorithm was tested on a nonlinear model of the obj ect, taking into account the limitations imposed on the control effect. In addition, an algorithm for discrete control of the feeder drive was developed and a comparative analysis of analog and discrete control systems was carried out. As a result, it was found that with the required dosing accuracy not exceeding 1 %, it is most expedient to use a discrete control system.
