In this paper, the authors investigates the usage of Fuzzy Logic Controller (FLC) in controlling the liquid level in the second tank of coupled-tanks plant through variable manipulation of liquid pump in the first tank. System modeling involves developing a mathematical model by applying the fundamental physical laws of science and engineering. Simulation studies are then conducted based on the developed model using MatlabR2012a for Simulink. In this papers also study behavior system in terms of time response (e.g., steady state error, a certain rise-time, and overshoot) and compare FLC adverse PID controller.
