在硬盘驱动器（HDD）的定位系统中，存在许多共振模式，它们彼此非常接近。因此，当采用曲线拟合方法时，难以获得精确的模型，并且难以抑制这些共振和任何干扰的影响。本文采用频域试验模态分析技术——微分迭代法，得到了硬盘定位系统的精确模型。采用鲁棒控制器设计方法设计的控制器、利用HDD定位系统精确模型计算的逆模型加前置滞后滤波器和在高频范围内加陷波滤波器抑制谐振影响的前置滞后滤波器，对三种控制器的控制性能进行了比较。在数值仿真中对各控制器的控制结果进行了比较。
In the positioning system of a hard disc drive (HDD), many resonance modes exist, and they are very close each other. Therefore, it is difficult to obtain a precise model when the curve fitting method was used and it is difficult to suppress both the effect of these resonances and that of any disturbances. In this paper, a differential iteration method that was one experimental modal analysis technique in the frequency domain is applied to obtain the precise model of a positioning system of a HDD. Three controllers 1) a controller which was designed using a robust controller design method, 2) a lead-lag filter that adds on the inverse model that was calculated using a precise model of the positioning system of a HDD, and 3) a lead-lag filter that adds on the notch filter to suppress the effect of resonance in the high frequency range were used to compare the control performance. We compare the results of each controller in numerical simulation.
