Abstract: Abstract In this paper, we address periodic disturbance rejection for sampled-data control systems, where the frequency of the disturbance can be beyond the Nyquist frequency of the limited measured plant output sampling rate. The disturbance… read more here.

Abstract: Abstract In digital/sampled-data motion control systems, the system outputs are only available at certain rates. This sets a great challenge to high-precision motion control systems that subject to high-frequency disturbances, since the feedback regulator cannot… read more here.

DOI: 10.1049/el.2020.0425
Abstract: A background calibration technique for time-interleaved analogue-to-digital converter (TIADC) over Sub-Nyquist frequency timing mismatch is proposed. When the input signal only satisfies the Nyquist sampling theorem of the overall TIADC rather than sub-ADC, both directions… read more here.
