S. Torres and Leizer Schnitman Chapter 19 Survey on Design of Truss Structures by Using Fuzzy Optimization Methods 393 Aykut Kentli Preface The search for the development of intelligent systems and emerging technologies has attracted so much attention over the centuries and created relentless research activities. The development of robotics and intelligent machines that have similar behavior to humans performing day to day activities is one of the greatest challenge scientist and researchers have to undertake. The quest and discoveries of new concepts and theories for intelligent non-conventional control systems denote significant technology developments that capture new territory for the betterment of humanity. To date, creating new technologies and innovative algorithms is the focused of research and development. Fuzzy logic system is one of the innovative algorithms that showed promising results in developing emerging technologies. Fuzzy logic was first proposed in 1965 by Lotfi A. Zadeh of the University of California at Berkeley. Fuzzy logic is based on the idea that humans do not think in terms of crisp numbers, but rather in terms of concepts. The degree of membership of an object in a concept may be partial, with an object being partially related to many concepts. By characterizing the idea of partial membership in concepts, fuzzy logic is better able to convert natural language control strategies in a form usable by machines. The application of fuzzy logic in control problem was first introduced by Mamdani in 1974. This book exhaustively discusses fuzzy logic controls, concepts, theories, and applications. It is categorized into three sections, namely: 1. Robotics and Electrical Machines. 2. Control Systems 3. Concepts and Theories In section one, there are four chapters that focus on fuzzy logic applications to robotics, particularly: 1. Humanoid Robot - Design and Fuzzy Logic Control Technique for its Intelligent Behaviors 2. Application of Fuzzy Logic in Mobile Robot Navigation 3. Modular Fuzzy Logic Controller for Two-Wheeled Wheelchair X Preface 4. Fuzzy Control System Design and Analysis for Completely Restrained Cable- Driven Manipulators The next two chapters are focus on fuzzy logic applications to electrical machines, namely: 1. Control and Estimation of Asynchronous Machines using Fuzzy Logic. 2. Application of Fuzzy Logic in Control of Electrical Machines. In section two, there are seven chapters that focus on control systems, particularly: 1. Fuzzy Logic Control for Multiresolutive Adaptive PN Acquisition Scheme in Time-Varying Multipath Ionospheric Channel 2. Fuzzy Control in Power Electronics Converters for Smart Power Systems 3. Synthesis and VHDL Implementation of Fuzzy Logic Controller for Dynamic Voltage and Frequency Scaling (DVFS) Goals in Digital Processors 4. Precision Position Control of Servo Systems Using Adaptive Back-Stepping and Recurrent Fuzzy Neural Networks. 5. Operation of Compressor and Electronic Expansion Valve via Different Controllers 6. Intelligent Neuro-Fuzzy Application in Semi-Active Suspension System 7. Fuzzy Control Applied to Aluminum Smelting Finally, section three consists of six chapters dedicated to concepts and theories, particularly: 1. Rough Controller Synthesis 2. Switching Control System Based on Largest of Maximum (LOM) Defuzzification; Theory and Application 3. A Mamdani Type Fuzzy Logic Controller 4. Tuning Fuzzy-Logic Controllers 5. Fuzzy Control: an Adaptive Approach Using Fuzzy Estimators and Feedback Linearization 6. Survey on Design of Truss Structures by Using Fuzzy Optimization Methods The contributions to this book clearly reveal the concepts and theories of fuzzy logic as well as its importance and effectiveness to the development of robotics, electrical machineries, electronics and intelligent control systems. The readers will find this book a unique and significant source of knowledge and reference for the years to come. Elmer P.
