Customizable Coherent Servo Demodulation for Disk Drives
نویسنده
چکیده
This paper describes the Customizable Coherent Demodulation Algorithm, a servo demodulator which provides dramatically improved performance over the currently used servo demodulation methods for disk drives. The demodulation algorithm proposed here makes better use of knowledge about the readback signal coming from the disk to provide better noise immunity and more immunity to other nonidealities in the magnetic head response. The net result is a demodulated Position Error Signal (PES) which has a much cleaner response.

by B.M. CHEN, T.H. LEE, K. PENG, and V. VENKATARAMANAN Iwas first introduced to disk drive servo systems as a graduate student under William Messner at Carnegie Mellon University. While my graduate work focused on control for distributed manipulation systems, most of my colleagues worked on projects for the Data Storage Systems Center. Our group meetings invariably focused on disk-drive-relevan...
متن کاملHigh-Gain Servo Controller for Optical Disk Drives and the Initial Value Compensation
As optical disks are removable and have some distortions, servo systems of optical disk drives must be robust, especially at low frequency. We proposed the high-gain servo controller with complex zeros, which is the same 2 order controller as conventional controllers, and realizes a much higher gain at low frequency. Decrease of servo error was confirmed, but the controller increased overshoot ...
متن کاملDesign of a Sliding Controller for Optical Disk Drives
This paper presents the design and implementation of a sliding-mod controller for tracking servo of optical disk drives. The tracking servo is majorly subject to two disturbance sources: radial run-out and shock. The lateral run-out disturbance is mostly repeatable, and a model of such disturbance is incorporated into the controller design to effectively compensate for it. Meanwhile, as a shock...
متن کاملRobust Adaptive Control of Hard Disk Drives with Hysteresis Friction Nonlinearity in Mobile Applications ⋆
In this paper, robust adaptive NN control is investigated for small form factor hard disk drives which is mainly used in mobile applications. The hysteresis friction nonlinearity from the pivot bearing degrades the servo performance, as hard disk drive servo system operates in track-following mode. To deal with the effect of hysteresis friction nonlinearity, adaptive hysteresis friction compens...
متن کاملOptimal H∞ Control Design and Implementation of Hard Disk Drives With Irregular Sampling Rates
Missing position error signal sampling data in hard disk drives (HDDs) results in their servo systems having irregular sampling rates (ISRs).With the natural periodicity ofHDDs, which is related to the disk rotation, HDD servo systems with ISRs can be modeled as linear periodically time-varying systems. Based on our previous results, an explicit minimum entropy controller for HDD servos with IS...
