Abstract: Aiming at the power unbalance problem of the head and tail motors during actual working conditions of scraper conveyor, power coordinated control system of scraper conveyor based on CANopen protocol was studied and designed. The system’s whole scheme design was introduced, coordinated control strategy was analyzed, and its hardware structure and software design were elaborated. The test results of experimental platform showed that, based on CANopen communication and rotary speed of motors regulated with real-time load change, the system can realize power coordinated control of two motors under the condition of load fluctuation effectively. It provides a new idea for study on power control of drive motors of scraper conveyor.
