Web Guide Process in Cold Rolling Mill : Modeling and PID Controller

摘要: There are many intermediate web guides in cold rolling mills process such as CRM (cold mill), CGL (continuous galvanizing line), EGL (electrical line) and so on. The main functions of the to adjust center line (strip) steel process. So they called CPC (center position control). Rapid speed cause large deviation between strip line. Too much is not desirable. difference should be compensated. In general, control obtained by hydraulic driver electrical controller. this paper, we propose modelling several controller designs for web-guide systems. We model guide using geometrical relations ignored mass stiffness web. To systems, PID controllers with their gains tuned Ziegler-Nichols method, H∞ model-matching coefficient diagram method (CDM). CDM modified high order results verified computer simulations.
