This document discusses fuzzy logic control for liquid flow systems. It begins by introducing the basics of liquid flow measurement and control, noting that factors like viscosity, density, and pipe friction affect flow rate. It then discusses the main components of a fuzzy logic controller, including fuzzification, a rule base and inference engine, and defuzzification. The document formulates the problem of measuring and controlling liquid flow rates given various disturbances. It proposes using a fuzzy logic controller instead of a conventional PID controller due to the former's robustness with imprecise models. Finally, it mentions that MATLAB will be used to implement and test the fuzzy logic controller.
