在硬盘驱动器（hdd）中，位置误差信号（PES）的采样周期受到限制。因此，多速率控制设计一直是硬盘领域的研究热点。本文提出了一种基于多速率采样数据H/sub /spl //控制理论的读写头定位控制器的设计方法。该方法可以直接考虑样本间性能和鲁棒稳定性来设计多速率控制器。讨论了广义植物的结构和加权函数的选择。通过实验，将所获得的性能与单速率采样数据H/sub /spl //控制器和单速率/多速率离散时间H/sub /spl //控制器进行了比较。
In hard disk drives (HDDs), the sampling period of a position error signal (PES) is restricted. Thus, the multi-rate control design has been a popular subject in HDDs. This paper proposes a design method of read/write head-positioning controller using multi-rate sampled-data H/sub /spl infin// control theory. This method can design multi-rate controller directly considering inter-sample performance and robust stability. The structure of generalized plant and the selection of weighting functions are discussed. The obtained performance is compared with the single-rate sampled-data H/sub /spl infin// controller and single-rate/multi-rate discrete-time H/sub /spl infin// controller through experimentation.
