Abstract—In this paper, it will be shown that ANFIS network is capable of identification of non-linear systems. Also, the fuzzy logic can simply control the system. The mentioned non-linear system is a control system of the liquid level which can be modeled by use of ANFIS network. After modeling stage, a fuzzy controller will be designed in order to achieve a desired liquid level. It will be proved that a fuzzy input-output controller acts like a PD controller. A PI controller will be added to the system in order to remove the steady-state error. Finally, we will design a fuzzy PID controller.
Index Terms—Fuzzy PID Controller, ANFIS method, liquid level, non-linear.
