Available in PDF, EPUB and Kindle. Book excerpt: Edited by Takashi Yamaguchi, Mitsuo Hirate, and Chee Khiang Pang, with contributions from pioneers known for their ground-breaking work, High-Speed Precision Motion Control discusses high-precision and fast servo controls in hard disk drives (HDDs). The chapter authors describe the control technologies they’ve developed, most of which have already been successfully applied to mass production of HDDs. As the proposed methodologies have been verified on commercial HDDs at the very least, these advanced control technologies can also be readily applied to precision motion control of other mechatronic systems, e.g., scanners, micro-positioners, photocopiers, atomic force microscopes (AFMs), etc. Each self-contained chapter progresses from concept to technique and presents application examples in automotive, aerospace, aeronautical, and manufacturing engineering. The control technologies are categorized into high-speed servo control, precision control, and environment-friendly control, making it easy to find an appropriate control technology according to their domain of application. The book also makes MATLAB®/SIMULINK® codes for benchmark problems available for download. The control technologies described range from fundamental classical control theories to advanced topics such as multi-rate control. The content contains a healthy balance between materials from the contributor’s research works and that in the wider literature. The resulting resource empowers engineers and managers with the knowledge and know-how to make important decisions and policies.

This book was released on 2017-12-19 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechatronic systems are used in a range of consumer products from large-scale braking systems in vehicular agents to small-scale integrated sensors in mobile phones. To keep pace in the competitive consumer electronics industry, companies need to continuously improve servo evaluation and position control of these mechatronic systems. Advances in High-Performance Motion Control of Mechatronic Systems covers advanced control topics for mechatronic applications. In particular, the book examines control systems design for ultra-fast and ultra-precise positioning of mechanical actuators in mechatronic systems. The book systematically describes motion control design methods for trajectory design, sampled-data precise positioning, transient control using switching control, and dual-stage actuator control. Each method is described in detail, from theoretical aspects to examples of actual industry applications including hard disk drives, optical disk drives, galvano scanners, personal mobility robots, and more. This helps readers better understand how to translate control theories and algorithms from theory to design and implementation in realistic engineering systems. The book also identifies important research directions and advanced control techniques that may provide solutions for the next generation of high-performance mechatronics. Bridging research and industry, this book presents state-of-the-art control design methodologies that are widely applicable to industries such as manufacturing, robotics, home appliances, automobiles, printers, and optical drives. It guides readers toward more effective solutions for high-performance mechatronic systems in their own products.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, the design of servo control algorithms is investigated to produce high-density and cost-effective hard disk drives (HDDs). In order to sustain the continuing increase of HDD data storage density, dual-stage actuator servo systems using a secondary micro-actuator have been developed to improve the precision of read/write head positioning control by increasing their servo bandwidth. In this dissertation, the modeling and control design of dual-stage track-following servos are considered. Specifically, two track-following control algorithms for dual-stage HDDs are developed. The designed controllers were implemented and evaluated on a disk drive with a PZT-actuated suspension-based dual-stage servo system. Usually, the feedback position error signal (PES) in HDDs is sampled on some specified servo sectors with an equidistant sampling interval, which implies that HDD servo systems with a regular sampling rate can be modeled as linear time-invariant (LTI) systems. However, sampling intervals for HDD servo systems are not always equidistant and sometimes, an irregular sampling rate due to missing PES sampling data is unavoidable. With the natural periodicity of HDDs, which is related to the disk rotation, those HDD servo systems with missing PES samples can be modeled as linear periodically time-varying (LPTV) systems. For the control synthesis of HDD servos with irregular sampling rates, an explicit optimal H_infinity control synthesis algorithm for general LPTV systems is first obtained by solving discrete Riccati equations. Then, the optimal H_infinity track-following control for irregular-sampling-rate servos is synthesized. Simulation and experiment studies, which have been carried out on a set of actual single-stage hard disk drives, demonstrate that the proposed control synthesis technique is able to handle irregular sampling rates and can be used to conveniently design a track-following servo that achieves the robust performance of a desired error rejection function for disturbance attenuation. Moreover, experiment results show that compared to the currently-used methodology for irregular sampling rates, the proposed control algorithm has significantly improved the servo performance. In addition, the feedback signal in HDD servos is generated from the servo patterns that must be pre-recorded using servo track writing process before the HDD can be used. Thus, the quality of the servo track writing process is also crucial to the accuracy of positioning read/write head. Recently, self-servo track writing has been developed in order to improve the quality of the written servo patterns and reduce the cost of servo track writing process. This dissertation considers two novel controller synthesis methodologies employing a feedforward control structure for performing concentric self-servo track writing in hard disk drives. Simulation results confirm that the two proposed control synthesis methodologies prevent error propagation from the previously written tracks and significantly improve servo track writing performance.
