Comparative analysis of electric drive control systems for technological facilities in the agricultural sector

Abstract

The article provides a comparative analysis of the most common electric drive control systems: scalar control, vector control and direct torque control DTC. The analysis is carried out according to the criteria for the performance of the torque loop, the robustness of the systems, the level of torque ripple and overshoot in the torque loop. Comparison is made by subjectively assigning points for each of the criteria based on a qualitative assessment. The simplified mathematical models are used for analysis, that taking into account the pulsating moment pulsations. In conclusion, it is concluded that it is advisable to use one or another control system for electrical equipment in various fields of agricultural use.
