本文针对数字控制系统中A/D转换器的速度慢于D/A转换器的速度限制，提出了一种新型的多速率两自由度控制器。所提出的前馈控制器保证了在M个采样点之间的完美跟踪。其次，将所提出的方法推广到时滞系统。将该方法应用于硬盘寻道控制中，验证了该方法的优越性。
In this paper, novel multirate two-degree-of-freedom controllers are proposed for digital control systems, where it is restricted that the speed of the A/D converters are slower than that of the D/A converters. The proposed feedforward controller assures the perfect tracking at M inter-sampling points. Next, the proposed method is extended to systems with time delay. The proposed scheme is applied to the seeking control for hard disk drive, and advantages of this approach are demonstrated.
