Abstract

The aim of this study is to develop a fuzzy blending hybrid controller (FBHC) which mixes the control outputs of a conventional PID and a fuzzy PID controller. The idea behind this design methodology is to combine the beneficial sides of both controllers in its own structure. The fuzzy and the conventional controllers are put into parallel form within this the blending mechanism and generally the advantages of conventional controller in steady-state characteristics and the fuzzy controller in transient characteristics are exploited. In this paper, a new hybrid controller scheme with a blending mechanism that uses simple fuzzy rule base instead of complicated algorithms has been presented. Moreover, the proposed blending mechanism is independent of the type of controllers used in hybridization. Thus, this feature provides the designer an opportunity to use other control strategies within the same mechanism for different processes.
