Designing of Controllers for Non-Linear Liquid Level System with ANFIS Method


In this paper, it will be shown that ANFIS network is capable of identification of nonlinear systems. Also, the fuzzy logic can simply control the system. The mentioned nonlinear 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.
