A Variable Structure Approach to Step-by-step Control System for Coiler of Hot Rolling Mill

摘要：

Because of the collision between lap of strip steel and unit roller, too big an impact occurs during the initial coiling of previous coiler of hot rolling. Based on the real work process of coiler at worksite, an electro-hydraulic step-by-step system is developed in order that unit roller can evite the step automatically. A variable structure approach using sliding mode is presented for the mechanical model of step-by-step control system for coiler of hot rolling mill which is built at laboratory used for research work. The switching function is designed to ensure the system to have better dynamic performance. Simulation results show that the system may give rather accurate servo tracking result and is fairly robust to the system parameter variation and have better dynamic performance by the proposed approach.
