Written for researchers and postgraduate students in control engineering, as well as professionals in the hard disk drive industry, this book discusses high-precision and fast servo controls in hard disk drives (HDDs). The editors present a number of control algorithms that enable fast seeking and high precision positioning, and propose problems from commercial products, making the book valuable to researchers in HDDs. Each chapter is self-contained, and progresses from concept to technique, present application examples that can be used within automotive, aerospace, aeronautical, and manufacturing engineering. MATLAB/SIMULINK codes for benchmark problems are available for download, upon purchase.
