摘要
随着钢铁连铸的发展,结晶器振动技术的发展成为提高生产效率,改善铸坯产品质量的主要手段.基于先进的液压伺服技术,建立由电液伺服阀、伺服油缸等组成电液伺服激振系统,根据实际生产参数建立数学模型.同时还在研究中加入了改进式PID控制方法,并由MATLAB进行结晶器伺服系统仿真分析,证明控制方法对系统的快速性、精确性、稳定性都有显著提高,也说明了此系统具有很强的实用型.
With the development of steel continuous casting, crystallizer oscillation technology becomes an important measure to increase productivity and improve product quality. In this paper, based on the advanced hydraulic servo technology, a servo oscillation system is set up by electro-hydraulic servo valve, servo cylinder and so on. Digital models are then built according to actual production parameters. The improved PID control method is also introduced. Finally, MATLAB is adopted to simulate and analyze this system. The system is proved to be quick, accurate, stable and highly feasible.
