Implementation of Liquid Level Control System Based on Intelligent Control Algorithm
Using Siemens S7-1500 series PLC modules and MCGS touch screens,real-time monitoring and constant liquid level control of a dual-tank water system have been achieved.Without the need to establish a mathematical model of the controlled process,two intelligent control algorithms,fuzzy control and fuzzy integral control,were used to control the liquid level,and the advantages and disadvantages of the two intelligent algorithms were analyzed.The on-site experiments show that the fuzzy control algorithm has static errors,but the errors can be eliminated by adding integral control.The system has advantages such as strong visibility and good control performance.
