Numerical Simulation of Liquid Level Based on Admixture Control Calculate Method

In the petroleum and the chemical energy systems, the bottom liquid-level of the rectifying column is of much impact on the normal of work of the rectifying column. However, it is difficult to work out an exact mathematically model for the bottom liquid-level, which justifies the unsatisfactory results of regular control methods based on modeling. The fuzzy control method is a new intelligent control method. It is of much inborn superiority to control those plants which cannot be exactly mathematically modeled. As a result, this paper designs a fuzzy controller, adopt the admixture control calculate method to control the bottom liquid-level of the rectifying column. The results of simulation based on the fuzzy control toolbox of MATLAB show that this control scheme can make good accomplishment.
