英文摘要：

In order to realize the intelligent coordinated control of two motors＇ power in the course of double drive scraper conveyor running and balance the dynamic tension between two mesh points of both ends of the sprocket. The current signals of the motors at both ends of scraper conveyor were tested and extracted while they were running. Strain gauge was used to test the dynamic tension when scraper entered and left sprocket meshing. The fuzzy PID frequency control method is adopted to adjust the speed of the motor inteUigenfly. It can be achieved that tail motor compensate driving force to head motor. Ensure the balance of two motors＇ balance and the tension of the sprockets. The experimental test results show that, the scraper conveyer intelligent coordinated control system can achieve the power balance of both ends of the motors effectively, The tension differences of both ends of the sprockets remained the same. It provides an important technical means to improve the working efficiency and prolong the service life of the scraper conveyors.
