FIELD: computerized dc drives using slave control systems with variables changing in wide range. SUBSTANCE: electric drive has motor with current sensor 2 connected to output of converter 3; connected in series current setting element 4, inertial filter 5, PI current regulator 6 whose second input is connected to output of current sensor 2, and first integrating adder 7; second integrating adder 8; and three adding amplifiers 9-14; first adding amplifier 9 is connected through first input to output of second integrating adder 8, through second input, to output of current sensor 2, and through output, to one of inputs of second integrating adder 8 and to that of third adding amplifier 11; second adding amplifier 10 is connected through its first input to output of first integrating adder 7 whose second input is connected to current setting element 4 and through output, to other input of both integrating adders 7 and 8 and to input of third adding amplifier 11 whose output is connected to input of converter 3. EFFECT: enhanced transient stability of current regulation in electric drive. 1 dwg
