溶解性溶液浓度的控制方法设计及PLC实现
Designation of control method in concentration of solubility solution and it's PLC realization
摘要
Abstract
The control in concentration of solubility solution usually used off-line measuring method. This bring the great difficult for real-time control of concentration. For this, method that combined of cascade and ratio control is proposed. By the sugar water concentration to be the model object, the level and flow for cascade control, and the secondary steam amount and dilute fluid amount for ratio control. The temperature, pressure and concentrate for single loop control. The concentration is controlled by the combine method. The results show that the control method is stable and effective, and reach the expected effect, and it provides a valuable reference of solubility solution control.关键词
