摘要： A method and system are disclosed for compensating disturbance applied to a plant, such as a HDD component, controlled by a state control device having an estimator & controller. The estimator & controller is adapted to generate a first control signal in response to a state signal indicating an estimated state of the plant. A second control signal is generated by applying a transfer function H(s) having defined gain/frequency characteristics to a control signal derived from the first control signal. An overall control signal is generated in response to the second control signal and the control signal derived from the first control signal and applied to the plant.

摘要： There are provided a method and apparatus for high-speed compensating repeatable run-out in a hard disk drive. The method includes a) obtaining a value of a position error signal (PES) of the hard disk drive, the PES being a relative position signal of the head with respect to the center of the target track of the disk; b) determining whether the head is in the settling mode; c) if the head is in the settling mode, compensating the RRO error without feeding back the PES; and d) if the head is in the track-following mode, compensate the RRO error by feeding back the PES. Accordingly, an excessive RRO error is compensated. Even though the hard disk drive receives an external shock or is assembled in an offline servo writing manner, the performance of the hard disk drive does not deteriorate.
摘要翻译：提供了用于在硬盘驱动器中高速补偿可重复耗尽的方法和装置。该方法包括：a）获得硬盘驱动器的位置误差信号（PES）的值，PES是磁头相对于磁盘的目标磁道的中心的相对位置信号; b）确定头部是否处于沉降模式; c）如果头部处于稳定模式，则在不反馈PES的情况下补偿RRO误差; 和d）如果磁头处于跟踪模式，则通过反馈PES来补偿RRO错误。因此，补偿了过多的RRO误差。即使硬盘驱动器受到外部冲击或以离线伺服写入方式组装，硬盘驱动器的性能也不会恶化。

摘要： In a hard disk drive (HDD), biases are measured across all zones of a disk, and nonlinear bias components are extracted. Upon a change in operational condition of the HDD, biases are measured at two reference positions on the disk so as to estimate a corresponding change in a linear bias component across all zones of the disk. The bias at a given position of the disk is then calculated based on the estimated linear bias component and the extracted nonlinear bias component.
