Design of heuristic fuzzy logic controller for liquid level control
Elamari Elayan · 2014
The objective of this paper is to develop a heuristic fuzzy logic controller (FLC) capable of driving the liquid level in the tank to a given set point. Firstly, the procedure of how to design a (FLC), using graphical user interface (GUI) in MATLAB, is explained, all the steps of defining the fuzzy sets are illustrated in the fuzzy inference system (FIS);choosing the fuzzy membership functions for the inputs and the output, for the process of level control and it's limits, is done in membership function editor; editing the fuzzy rules that needed to control the level in a water tank is achieved with rule viewer using rule editor; Finally, the simulation results obtained were compared with a classical controller (PID Controller) are very satisfactory.
