Disturbance Observer-Based Control: Methods and Applications [Bookshelf]

This 340-page book is primarily based on the authors’ extensive ten-year research effort on disturbance-observer-based control (DOBC) theory and applications. The book covers the theoretical analysis of both basic and advanced concepts in DOBC, as well as engineering applications in process control, mechatronics, and flight control systems. The target audience is both researchers working on advanced control methods and related engineering fields and practicing engineers interested in disturbance estimation and compensation. This book attempts to fill the absence of an academic reference book on DOBC methods and applications, and, in this context, the authors provide a systematic perspective on the underlying philosophy of DOBC, its distinct features relative to other methodologies and design tools, and its major theoretical developments and application-related contributions. An ever-increasing demand for higher-precision control performance has been observed in the modern control systems community, such as in mechatronics and robotics, electrical machines and drives, power electronics, energy conversion, and the aerospace and automotive sectors. DOBC has been known as one of the most promising and effective methods in the control community for quite a long time. While there are many research papers, few academic books exist on the subject, and the authors attempt to fill this void. The book is well written and clearly illustrates the contributions of DOBC alongside established techniques in disturbance rejection. All theoretical results are given with rigorous mathematical proofs. In the applications sections, the simulation results are elegantly presented with plenty of comparative studies. Although most of the mathematical concepts and abbreviations are defined throughout the book, a glossary or list of symbols and abbreviations would be a welcome addition. The book would be a useful resource for an advanced graduate course in control, for researchers in the areas of systems and control, as well as an educational reference for practicing engineers.
