Stable Iterative Feedback Tuning-based design of Takagi-Sugeno PI-fuzzy controllers

Abstract

The paper presents a new approach to the design of Takagi-Sugeno PI-fuzzy controllers employing Iterative Feedback Tuning (IFT). A Lyapunov-based original stability analysis algorithm guarantees convergent IFT algorithms. One case study focused on servo systems with second-order integral type controlled plants exemplifies the stable design accompanied by real-time experiments.
