We have developed a mill balance control system, which regulates the motor currents and rolling forces of tandem-cold-mill stands while maintaining finish gage accuracy.
The controller is designed using the ILQ design method and constructs a cascade loop outside an automatic-gage-control loop.
The experimental results showed that maximum rolling speeds have increased by 2.4% on average without deterioration of gage accuracy or strip shape.
