Abstract
This paper presents a precise identification technique for plant dynamic characteristics under the restricted sampling rate of A/D and D/A converters. The proposal technique can expand the identification frequency range based on an interpolation method, achieving twice frequency bandwidth as original Nyquist frequency at the identification. The effectiveness of the proposed identification was verified by the results for the head positioning system in hard disk drives.
