Electromechanical system of the asynchronous electric drive of movement of a bridge crane modeling

Abstract

The method of electromechanical system of electric bridge crane with asynchronous motors modeling, which provides a skew correction and lateral displacement of the crane with high speed and accuracy, is presented. Results of modeling are shown. The direct torque control system is applied to control asynchronous motors. Four contactless distance sensors are used to analyze the position of the crane and identify the skew of the crane relative to the crane tracks. By means of software package in Universal Mechanism, a mechanical model of an overhead crane was developed with a high degree of details. Simulation of power electric part and control system was produced in the MatLab/Simulink software package. The developed models of mechanical and electrical subsystems are combined through the UM Cosimulation interface into an integrated electromechanical model of the overhead crane for analysis of dynamic processes.
