针对国内某冷轧薄板酸洗生产线带钢对中装置存在的问题,提出了设备改造方案,进行了液压系统的机械及控制系统改造设计,设计了模糊自整定PID控制器并进行了仿真研究,结果表明该控制器能够满足实际工作的要求。
Aiming at the existing problems of strip centering in a domestic cold-rolled sheet pickling production line, a scheme of equipment reform was put forward. The design of the mechanical and control system of the hydraulic system was reformed. The fuzzy self-tuning PID controller was designed and simulated. The results show that the controller can meet the requirements of practical work.
