FIELD: computerized electric drives.
SUBSTANCE: proposed control system designed for controlling group of parallel-running induction-motor drives of water pumps has multiple-section pulse-width frequency scanning converter built around integrator adders and relay components, memory register, digital comparator, monostable multivibrator, and group of parallel-running actuating mechanisms (pumps) controlled by induction motors incorporating voltage regulators.
EFFECT: enhanced precision.
