Stability Analysis of Fuzzy-Model-Based Control Systems: Linear-Matrix-Inequality Approach

Detailed Summary of the Book

The foundation of this book lies in fuzzy logic and its application in control systems. Fuzzy-Model-Based (FMB) control systems provide a robust modeling mechanism for handling uncertainties and nonlinearities often present in real-world systems. While FMB systems present significant advantages, analyzing their stability is a challenging task, especially for complex dynamic processes. This book effectively bridges the gap by utilizing the Linear Matrix Inequality approach, a robust mathematical optimization tool.

The authors offer a systematic discussion on fuzzy rule-based systems and how they are transformed into Takagi-Sugeno (T-S) fuzzy models. These models are analyzed for stability conditions using LMI modeling, which simplifies complex stability problems into solvable convex optimization tasks. Several stability criteria applicable to nonlinear systems are discussed, providing readers with theoretical foundations and practical tools for diverse applications in engineering and beyond.

The book is structured to progress from fundamental concepts to more advanced topics. It covers stability criteria, robust control, observer design, as well as computational methods for solving LMIs effectively. By including numerical examples, case studies, and illustrative scenarios, the book helps readers apply the theoretical findings to real-world problems.
