The results of the analysis of quality indicators of the proposed control systems for the electric drive of the DMZ ore yard with rheostatic tilt speed control, using alternative the system "thyristor converter - DC motor" and "frequency converter - induction motor", by studying the transients of these electric drive systems using the software product Matlab. It is established that the parameters of the control system "frequency converter - induction motor", are not inferior to the parameters of the control system "thyristor converter - DC motor", and even slightly exceed it, in particular, in the range of technological speeds of the wagon tipper drive, and energy losses during transient start-up processes are 2.3% less than the "thyristor converter - DC motor". It is expedient to use the offered decisions in case of modernization of the operating electric drive of the wagon tipper.
