Abstract

The development of a control system for the electric drive of the mine network is a promising area of research that allows precise control over the parameters of the electric drive (the speed of movement of the lifting vessel, the force of the cargo winch, the excitation current).

The study purpose is to create a model of dynamic processes of an electric drive for studying the functioning of a skip lifting unit in a mine network.

Materials and methods. Modeling of dynamic processes in the electric drive of the lifting unit during the movement of the lifting vessel according to a given tachogram was performed in the MATLAB environment. Mathematical modeling methods were used to study the behavior of the electric drive control system under the specified control loop settings, as well as reconfiguration of the circuits to obtain the required transients. The modeling was carried out taking into account the assumption that all elements of the model are represented by the corresponding transfer functions.

Results. The calculation and adjustment of the main transfer functions of the excitation current regulator, the current of the anchor circuit, and the speed control of the electric drive were performed. The results of experimental measurement and modeling are compared in the MATLAB software package.

Conclusions. As part of the study, dynamic processes of the electric drive of the mine network lifting unit were simulated in the MATLAB software package and a control system was developed that allows you to control the operation of a DC electric drive.
