FIELD: machine building.
SUBSTANCE: invention relates to redundant control systems, in particular, systems for controlling drives. Three-channel control system is proposed, which contains three control channels, each of which contains a computing unit containing a computer and a transceiver of a serial interface connected to a computer made with synchronization inputs and synchronization outputs, the synchronization outputs are connected to the corresponding synchronization inputs of the computer of the other two channels. Additionally, the system contains two blocks of resistors, and each of the control channels additionally contains a PWM signal output unit, an analog signal input unit, and a switching amplifier.
EFFECT: technical result of the claimed invention is to improve the reliability of the device and the accuracy of drive control by automatically switching to a healthy channel while managing unreserved load (redundant duplication) and reducing the influence of destabilizing factors on control accuracy.
