Scalar control of a marine electric drive with a brushless magnetoelectricmotor

Abstract

The aim of the work is to develop scientific and methodological foundations for the analysis and synthesis of systems of subordinate regulation by an electric drive with a synchronous magnetoelectric motor with position-dependent con-trol from a valve switch. The article analyzes the valve magnetoelectric motor as a control object, evaluates its transient characteristics, shows the possibility of using the principles of subordinate regulation and its advantages in comparison with vector control of the internal coordinates of the object. The paper points out the features of the formation of a block diagram for the speed control circuit. As a result of the research, the method of synthesis of the speed controller of the subordinate control system, as an analogue of an electric drive with a DC collector motor, is given. The possibility of applying the principles of subordinate regulation for an electric drive with a magnetoelectric valve motor is proved. The features of the technique for the synthesis of the frequency regulator are shown. The features of its implementation in an electric drive with a brushless magnetoelectric motor in comparison with a DC electric drive are shown.
