摘要：

To address the problem of improving the positioning accuracy of the read write head of hard disk drives (HDDs), we present a tuning methodology for the HDD servo controller based on the fixed-structure H∞ controller optimization. Since optimization is carried out under the fixed controller structure without any additional sensor, no extra cost is introduced. The effectiveness of the proposed method is demonstrated by simulation and experimentation.
