The Research on Load Balance Controller of Roller Single Roller Drive System Based on Fuzzy PID

摘要

In order to solve the load imbalance problem of the single-roller transmission system of the rolling mill, this paper adopts a cross-coupling method to achieve synchronous control between the two motors. A fuzzy proportional-integral-derivative (PID) load balance controller is designed to solve the load balance controller input Unbalanced rolling mill load caused by single factor and improper control algorithm. At the same time, in order to improve the synchronization performance of the motor, a PI tracking controller was designed. Finally, Simulink simulation tools are used to verify the effect of the load balancing controller on the effect of synchronous control of dual motors. The simulation results show that compared with the control strategy of traditional PID as the controller algorithm, fuzzy PID as the controller can reduce the overshoot and speed up the response, ensure the output of the upper and lower rollers is balanced, and also keep the motor within a safe range, balance.
