Research and Simulating Electric Drive System of ЭKΓ–10 Excavator by Matlab Simulink Software

Thi Thuy Nguyen

Abstract


The ЭKΓ - 10 is a new Russian excavator that uses a converter generator motor drive system. It replaces traditional drive systems: magnetic amplifier- generator-motor by a motor-generator-converter system. The electric drive system of the ЭKΓ - 10 excavator uses a converter-generator-motor with a flexible working model, which meets high requirements according to the "excavator type” working characteristics. This drive system uses microcontrollers combine closed-loop control method to change the control angle of the converter therefore it changes the generator's voltage and motor to adjust the speed of the motor. That it has marked a new turning point in the automation of the control process to production, the Excavator drive system is very complex, consisting of many mechanisms structures, so the system's operation requires a perfect controller in both parameters and control techniques. In other words, to improve the productivity and quality of operation of this type of excavator, it is necessary to find a suitable working parameter for the controller of the electric drive system. The article has researched and simulated the converter-generator-motor drive system of the ЭKΓ - 10 excavators by Matlab Simulink software to find out the optimal parameters to meet the operation requirements of the system and have the direction of control match the load object when they constantly change, thereby helping the system operate stably and achieve the desired control quality.

Keywords
