Redundant, Autonomous Decentralized Control System for Super High Power Motor Drive

Super high power motor control is confined by the control method and structure, which currently is centralized control method. This method requires corresponding super high power supply, which is the obstacle of this issue. In this paper, an autonomous decentralized system for super high power motor is, for the first time, proposed. As a first step, the architecture of the autonomous control model was analyzed, and then the fault-tolerance configuration was designed. An experimental system was built and the designed algorithm was implemented and evaluated on the test bench. The system we proposed is supposed to be highly fault-tolerant and allowing the distributed power transmission which can reduce the burden of the power supply. The test results confirmed the validity of the proposed system.
