Abstract

A method is proposed and the possibilities of using the application program Simulink of the MATLAB package for analyzing the characteristics of a special electric drive based on an asynchronous electric motor are considered. A special feature of the electric drive is the working machine. The moment of resistance of the working machine depends nonlinearly on the speed of the electric drive. The actuator uses system Direct Torque Control. Methods for analyzing the stability of the operation of an electric drive in the most severe operating modes - starting and changing the control action - are considered.
