Abstract

The invention discloses a high-precision position control system for a belt type transmission device. The system is characterized by comprising a direct-current brushless servo motor and a speed reducer connected to the direct-current brushless servo motor, and a central shaft of a conveying belt is electrically connected to the direct-current brushless servo motor through a coupler; and an OPC client is connected to an OPC server, the OPC server is connected with a PLC, and the PLC is connected with the direct-current brushless servo motor for real-time control. According to the invention, a PID algorithm is realized in the PLC, the functions of fuzzy operation and judgment are realized by applying MATLAB, and the two functions are organically combined through an OPC technology, so that the real-time online fuzzy self-tuning of PID parameters is realized, and the stability and accuracy of the motor in a load state are improved.

Description

technical field [0001] The invention relates to a high-precision position control system and method of a belt transmission device, belonging to the technical field of transmission control. Background technique [0002] The belt transmission device has the advantages of strong continuity, high efficiency, and large transportation volume, which is of great significance for improving the safety, reliability and stability of the automatic conveyor line. The motor drive form and intelligent control method of the belt transmission device are currently research hotspots. [0003] The position accuracy of the belt transmission device under load changes is too low, that is, when the conveyor line is continuously started and stopped at high speed for a long time, it is easy to cause unstable transportation due to changes in the motor load, and it needs to be optimized. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the pri...
