FIELD: DC motor current control. SUBSTANCE: mean current discriminating device, second and third adders, and mean current error control are newly introduced in motor current control system. Input of mean current discriminating device is connected to output of current sensor signal amplifier and its output current is subtracted from current setting unit signal at second adder. Output current of second adder is passed to mean current error control and its output current is added at third adder to output value of setting current signal amplifier thereby organizing circuit for controlling inconsistency between desired and actual values of mean current. As a result, full consistency is ensured between desired and actual values of motor armature mean current thereby raising accuracy of motor current control by 0.3 to 3%. EFFECT: improved accuracy of current control. 3 dwg
