FIELD: electricity.
SUBSTANCE: control system contains section drives controlled by a microprocessor device the sections including electric motors, their output shafts connected to the operating mechanisms transmissions, with power transformers installed at the output. Additionally introduced are speed sensors and adders; a speed regulator is installed, its output connected to the power converter input. Connected to the speed regulator first input is a multiplier output. Connected to the speed regulator second input is the output of the second frequency-to-number converter. Additionally installed is the material tension regulator. Additionally introduced into the system are a reference model, an updown counter and two adder units. The reference model is connected to the counter adding input and the first adder first input via the frequency-to-number converter. Connected to the subtracting input of the counter is the output of the pulse speed sensor mounted on the second section shaft. Via the frequency-to-number converter the same output is connected to the second input of the first adder the output whereof and the counter output are connected to the inputs of the second adder the output whereof is connected to the speed regulator third input.
EFFECT: enhanced accuracy of regulation and stability of the second drive system operation at variable parameters of the first drive.
