Level Control Study of Two-link Tank on Double Baroceptors

Abstract

The level of two-link tank was controlled for THKGK-1 advanced process control device based on double baroceptors. The method of PID control and fuzzy control were used respectively to control liquid level on the existing experiment equipment and software environment. During the experiment, firstly, PID control experiment was done on single baroceptor. Then the experiment was repeated on double baroceptors, and observation and analysis control effect was done according to the actual control results. Secondly, fuzzy control method was put forward and a fuzzy controller was designed by analysis experimental results to find the shortages, and then experimental verification work was done. Finally, the real-time curve of level control and real-time data were displayed in the MCGS configuration software. The two experimental results show that PID Control can control the level of twolink tank, but the effect is a bit poor. It can be improved the performance using PID control based on double baroceptors. The fuzzy control improves the dynamic performance and steady-state performance and obtains better control effect.
