Research on power balance control of scraper conveyor based on fieldbus
Taking the scraper conveyor in the fieldbus control system as the research object,the structure of the whole system and the advantages of permanent magnet synchronous motor as its drive system over asynchronous motor was introduced.The maximum torque current ratio control was selected as the control mode of the drive system,aiming at the power imbalance problem of multi-motor scraper conveyor,a master-slave control mode of torque distribution was proposed to control it,a double-motor driven scraper conveyor model was built on the AMESim platform,and a permanent magnet synchronous motor control system was built on the MATLAB/Simulink.The proposed maximum torque current ratio control and the master-slave control scheme of torque distribution were simulated and verified.The fieldbus technology and the control strategy were applied to the actual system,and good results were obtained,and the feasibility of the proposed scheme was verified.
