| Abstract: | In order to improve the width control precision of hot rolling strip, the automation width control technology of Hot Rolling Strip was developed. On the base of the research for SSC and AWC, rolling force feedback control system based fuzzy-PID controller was used for adjusting roller sew. The simulation result and locale application indicated that the more perfect control effect was obtained using fuzzy-PID control and the qualified product radio was increased to 97% from 94%. |
