一种自适应液位控制算法在滤汁快沉中的应用研究

摘要

在糖厂的滤汁快沉系统中，滤汁平衡箱液位受进、出口管道流量等因素影响而出现偏离正常值范围，需借助人工操作完成液位调节。为了减少人工操作，本文根据采集到的关键数据及选择性控制算法，设计一套基于数据关系模型分析及选择性液位控制的自适应液位控制算法，实现快沉系统中的平衡箱液位由异常状态向正常状态的自动切换，进一步增强快沉控制系统的自适应性。%The liquid level of balance tank affected by import pipeline flow and export pipeline flow, which would result in the level deviation from the permitted range in accelerated clarifier system of filter juice, and the liquid level regulation must be completed by manual operation in sugar mill. According to the collected key data and selective control algorithm, the adaptive liquid level control algorithm was designed based on relational data model and selective level control in order to reduce the manual operation, which realized the liquid level of balance tank automatically changing from the abnormal state to the normal state and further enhanced the adaptivity of the accelerated clarifier control system.
