Research and Application of Hot Rolled Laminar Cooling System at JISCO
2008
The mathematic model for the control system was given.The basic principle and control method of the control system were discussed.Based on the model of strip in cooling process,feedforward compensation was implemented for the presetting model.And considering the uncertainty and long dead time of the model,fuzzy prediction control method was introduced,which promote the precision of feedback controlling.By analyzing the result of debugging system,the system may control the accuracy of cooling temperature in±8 ℃,and the product quality was improved greatly.
