Research on the Control System of the Rotary Feeding Based on the Coordinated Motion of Multi-motors
This paper introduces a new type of rotary feeding method for multi-motor coordinated motion of three-high Pilger rolling mill.The system is composed of seven motors working together,adopting double rotation and double feeding strategy,which completes rotation and feeding in the idling feeding area of the roll.In order to strengthen the coordination of servo motors,a ring coupling control structure is adopted,which coordinates the coupling relationship between multiple motors through a speed compensator.Simulations on the Simulink platform show that,compared with the traditional parallel structure control method,the ring coupling structure has better coordination performance,especially under load disturbance,the system performance is more stable.The new type of rotary feeding method and ring coupling control structure effectively improve the production efficiency of the pipe mill,and ensure the control accuracy and stability of the system.The research results provide a feasible control scheme for continuous rolling in the pipe industry.
