Application research on feedback control based on Dahlin algorithm for coiling temperature of hot strip

摘要

To improve the precision of the coiling temperature and the performance of the feedback control system with long pure time delay on hot strip mills,we analyzed the design process of the Dahlin algorithm in detail.The coiling temperature curves controlled by the PID algorithm and Dahlin algorithm were simulated and compared,which showed that the control precision with the Dahlin algorithm was higher than that with the PID algorithm.That was further verified by the production practice.
