英文摘要：

In order to extend the function of the process control device, a level control system experimental platform based on the NI data acquisition board PCI-6024E and LabVIEW development software is established. The virtual instrument technology is applied to the liquid level control system ,which has good flexibility ,transplantable charac- ters. PID control algorithm and the grey prediction PID control algorithm are designed based on LabVIEW and ap- plied in the dual-tank level control system and achieved good control effect, indicating the effectiveness of the experimental platform.
