IMPROVING CONTROLLERS QUALITY OF ELECTRIC DRIVE SYSTEMS FOR INDUSTRIAL MACHINES ON THE BASIS OF POWER CONVERTER - INVERTER

Abstract

The paper presents research on the calculation method of designing optimal
current control problem sets to improve the quality of inverter systems used in
industrial machine control with loads of, three phase AC asynchronous motors.
System kinetics to evaluate control methods. The main goal of adopting the
optimal control method of the energy flow to the converter and the three phase
inverter is to regulate the output current. The AC side has the desired sine wave
shape, the voltage across the ac phases is stable with low oscillation. The
simulation results when applying the proposed research method for the three
phase inverters were simulated on Matlab Simulink software. And experiment
with phase flow inverters has proven the advantages of the converter, the
proposed algorithm has improved the output voltage and current quality of
three phase inverters with industrial load.
