Real-Time Gain Identification

View page
US Patent:
20110216437, Sep 8, 2011
Filed:
Mar 3, 2010
Appl. No.:
12/716408
Inventors:
Priyadarshee D. Mathur - Shakopee MN, US
Peng Yan - Eagan MN, US
Chiyun Xia - Bloomington MN, US
Assignee:
SEAGATE TECHNOLOGY LLC - Scotts Valley CA
International Classification:
G11B 19/02
US Classification:
360 69, G9B 19001
Abstract:
A real-time gain identification system for a mechatronic system, such as a servo system, including at least two actuators is provided. In an example implementation, a servo system comprises a primary actuator and a piezoelectric secondary actuator. A controller generates a disturbance for one of the actuators that is compensated for (e.g., canceled) using another actuator. In one implementation, a gain of the actuator at an arbitrary time is calculated based upon a comparison of a signal used to compensate for the disturbance (e.g., cancel the disturbance) at that arbitrary time to a signal known to compensate for a disturbance (e.g., cancel the disturbance) under known conditions. For example, a gain may be determined based on a ratio of a signal used to cancel a disturbance at an arbitrary point to a signal known to cancel the disturbance under known conditions. Similar methodologies can be applied in other mechatronic systems with multiple actuators.

Compensation For Vibration In A Data Storage System

US Patent:
20130003219, Jan 3, 2013
Filed:
Jun 30, 2011
Appl. No.:
13/173841
Inventors:
Jeffrey Vincent DeRosa - Burlington MA, US
Bin Huang - Savage MN, US
Chiyun Xia - Prior Lake MN, US
John Lowell Zeller - Victoria MN, US
Peng Yan - Eagan MN, US
Assignee:
SEAGATE TECHNOLOGY LLC. - Cupertino CA
International Classification:
G11B 21/02
US Classification:
360 75, G9B 21003
Abstract:
A plurality of sensors are used to sense disturbances in a data storage system. An adaptive gain component is associated with each of the sensors and provides a gain for each of the sensor signals. The gain of each sensor signal is adapted, individually, based on a correlation of each given sensor signal to the position error signal. This adaptation produces a position correction signal. The position correction signal is applied to a position signal that is used to position the reading and writing components and the storage medium relative to one another. This compensates for both rotary and linear vibration disturbances at the same time.

Methods And Devices For Compensating For Off-Track Motion

View page
US Patent:
20130128380, May 23, 2013
Filed:
Nov 21, 2011
Appl. No.:
13/300920
Inventors:
Timothy E. Langlais - Minneapolis MN, US
Ju-IL Lee - Eden Prairie MN, US
Frank W. Bernett - Longmont CO, US
Chiyun Xia - Prior Lake MN, US
International Classification:
G11B 21/02
US Classification:
360 75, G9B 21003
Abstract:
In certain embodiments, a method includes sensing a mode of a motor-base assembly's response to vibration. Based on the sensed response, the method includes adjusting a head-suspension assembly to compensate for off-track motion caused by the vibration.In certain embodiments, an apparatus includes a sensor positioned on a basedeck such that the sensor senses a mode of the motor-base assembly's response to linear vibration.
