Notice of Violation of IEEE Publication Principles: Dissipativity-Based Fuzzy Integral Sliding Mode Control of Continuous-Time T-S Fuzzy Systems

TLDR

The study focuses on dissipativity‑based fuzzy integral sliding mode control of continuous‑time Takagi‑Sugeno fuzzy systems under matched and unmatched uncertainties and external disturbance. The authors propose an integral‑type fuzzy switching surface that accounts for the state‑dependent input matrix to better accommodate T‑S fuzzy models. They derive stability conditions via a Lyapunov function and transition matrix properties, synthesize a FISMC law to enforce sliding mode dynamics, and design a modified adaptive FISMC law to estimate the unknown upper bound of matched uncertainty. Two practical examples demonstrate the effectiveness and advantages of the proposed FISMC scheme. Notice of violation: author Hamid Reza Karimi inflated citations, violating IEEE ethical publishing principles.

Abstract

Notice of Violation of IEEE Publication Principles<br><br>After careful consideration by a duly constituted committee, an author of this article, Hamid Reza Karimi, was found to have acted in violation of the IEEE Principles of Ethical Publishing by artificially inflating the number of citations to this article. <br/> This paper is concerned with dissipativity-based fuzzy integral sliding mode control (FISMC) of continuous-time Takagi-Sugeno (T-S) fuzzy systems with matched/unmatched uncertainties and external disturbance. To better accommodate the characteristics of T-S fuzzy models, an appropriate integral-type fuzzy switching surface is put forward by taking the state-dependent input matrix into account, which is the key contribution of the paper. Based on the utilization of Lyapunov function and property of the transition matrix for unmatched uncertainties, sufficient conditions are presented to guarantee the asymptotic stability of corresponding sliding mode dynamics with a strictly dissipative performance. A FISMC law is synthesized to drive system trajectories onto the fuzzy switching surface despite matched/unmatched uncertainties and external disturbance. A modified adaptive FISMC law is further designed for adapting the unknown upper bound of matched uncertainty. Two practical examples are provided to illustrate the effectiveness and advantages of developed FISMC scheme.
