Application of Fuzzy Control in a Wireless Liquid Level Simulator

Abstract

Liquid level control has great proposition in terms of chemical processes. It is important to make the level measurement in the tanks filled with industrial liquids with accurate and reliable equipment and to keep the liquid level at a certain level. In the studies conducted, wireless liquid level control was performed in a process control simulator system. For all computation and data processing procedures, the MATLAB program is used on-line connected to the system where the liquid level system is located. Then, the behavior of the output variable is examined by giving various effects to the liquid level valve opening selected as the setting variable. Fuzzy control of the system was performed by using the most suitable model found in the operating conditions obtained in dynamic studies. Wireless on-line computer control systems are used for this. The best control efficiency was obtained when the values were 4 dm.
