Abstract

Although a fuzzy logic controller is generally nonlinear, a PI-type fuzzy controller that uses only control error and change in control error is not able to detect the process non-linearity and make a control move accordingly. In this paper, a multi-region fuzzy logic controller is proposed for nonlinear process control. Based on prior knowledge, the process to be controlled is divided in fuzzy regions using an auxiliary process variable. Then a fuzzy controller is designed based on the regional information. Rule combination and controller tuning are discussed. Application of the controller to pH control is demonstrated.
