Power Balance Control of Scraper Conveyor Based on Permanent Magnet Synchronous Motor Drive
Taking the double-machine-driven scraper conveyor as the research object,the advantages of permanent magnet synchronous motor as its driving system compared with asynchronous motor are introduced,the maximum torque-current ratio control is selected as the control mode of the driving system,and for the power imbalance problem of the multi-motor scraper conveyor,the torque distribution master-slave control mode is proposed to control it,and finally the model of the double-machine-driven scraper conveyor with permanent magnet synchronous motor is constructed in AMESim platform,and the model of the double-machine-driven scraper conveyor in MATLAB/MATLAB is built in MATLAB/MATLAB.Finally,the scraper conveyor model with double-machine drive is built on AMESim platform,and the permanent magnet synchronous motor control system is built on MATLAB/Simulink,and the proposed maximum torque-current ratio control and torque allocation master-slave control scheme are simulated,and the results verify the feasibility of the proposed scheme.
