Abstract: Near net thin strip continuous cast rolling is a kind of new technique that use two rotating rolls as the crystallizer and cast the liquid metal between the two rolls to produce strip directly. The stability and accuracy of the casting roll speed are the key to the performance of the casting. A fuzzy variable parameter PID control technology is proposed. It is a dual ringwith layered structure, which consists of an out-side ring of traditional PID control and an inside ring of parameter governing. It can adjust PID parameter to make it updated according to working systems and overcome the effects resulting from the no 1inearity of systems . It can make the conditions relatively best. It is indicated by simulation results that variable parameter PID has better dynamic behaviors and stability of system than traditional PID. Key Words: continuous cast rolling; PID; fuzzy control; variable parameter
