Color and Height Control of Fluid Mixing System Using Fuzzy Logic

This paper presents a qualitative control of a fluid mixer, which is a non-linear plant. The mixer has as inputs two fluids of the resulting mix. The control system consists of two independent fuzzy controllers which are responsible for maintaining the water level at a given height and for adjusting the color of the fluid in the mixing tank. The main points studied are response when the desired color is changed and when the output flow changes. Simulation results show that approach of using two independent controllers, with simple rule-bases, can give good results. The simulation of fuzzy logic controller for a fluid mixing system using MAT LAB Simulink and MAT LAB Fuzzy Logic Toolbox. The Centroid (MAMDANI) method and center of gravity singleton method for defuzzification will be used in the inference engines.
