Design of Optimized PID Type Fuzzy Logic Controller for Higher Order System

Abstract

In this paper, a new structure of PID type fuzzy logic controller is proposed in which Fuzzy PI controller and conventional PD controller are connected in parallel. The gains of the proposed controller are calculated by Gradient descent optimization method. Illustrative examples are considered to validate the performance of the proposed structure. The proposed controller outperforms the Conventional PID Controller and existing fuzzy PID Controllers in terms of performance indices for a different plant.
