摘要
以串级控制和工业组态技术为基础对管道液位-流量系统进行研究,建立了系统数学模型,组建了系统的组态,采用PLC控制器,整定了PID参数,并进行了系统仿真,较好地解决了进水流量波动引起的液位控制精度不够的问题,同时有效提高了系统的动态性能。
The pipe water level-flow measurement system was researched based on cascade control and industry configuration technology. The system＇s mathematical model was established and monitoring system＇s configuration was created. By using PLC controller, PID parameters were set. The system simulation was carried on. The problem, which the precision control requesting for the fluid position system was not met because of flow fluctuation, was well solved. The dynamic performances of the system were effectively improved.
