Hard Disk Drive Servo Systems

Associate Professor Chen's research interests are in linear systems, robust control theory and control applications. He has published 7 monographs. He has served as an Associate Editor of IEEE Transactions on Automatic Control, and Asian Journal of Control. Currently, he is serving as an Associate Editor of Systems and Control Letters, and Control and Intelligent Systems. Before returning to Singapore, Professor Chen worked in the US (New York and Washington State Universites) and in Australia. He lectures on several courses, both undergraduate and graduate. Professor Lee's research interests are in intelligent systems and control, adaptive control and control applications. He has published hundreds of technical papers and several monographs. He is an Associate Editor of several international journals including Automatica, Control Engineering Practice, IEEE Transactions on Systems, Men and Cybernetics and International Journal of Systems Science. He is also serving as an Honorary Editor of IEE Proceedings - Control Theory and Applications, and a Regional Editor (Asia-Pacific) of Mechatronics. Doctor Peng's research interests incclude control theory and control applications to hard disk drive servo systems and flight control systems. Doctor Venkataramanan's current research focus is on topics related to hard disk drive servo systems, hyperflexible object manipulation and biological control.

From the reviews: I would consider this book to be must-read material for those directly involved in track-following or track-seeking controller design. The structural decomposition approach employed for linear systems provides an effective development framework for the authors' robust and perfect tracking (RPT) controller. The coverage of composite nonlinear feedback, which consistes of a linear controller in parallel with a nonlinear controller, is excellent, and the authors make a compelling case for its use in practice... I found the mathematical treatment to be quite dense, and would recommend this book only to those who have had graduate courses in both linear and nonlinear control. Thankfully, all of the control approaches represented in the book have convenient Matlab implementations in the authors' downloadable toolbox. As a whole, Hard Disk Drive Servo Systems is an invaluable addition to the practicing servo engineer's library... Perhaps the most valuable contributions are the Matlab toolbox and the benchmark problem. With these tools, the authors' claims can be tested and their results expanded upon.
