Abstract
This paper presents a discrete control design for
time-delay systems subjected to the periodical command
signal or exogenous disturbances. Unlike other deadtime
compensators (DTC), we take profit of the system
components to construct an internal model. In addition,
a novel disturbance observer is developed to compensate
the effect of disturbances, and thus to achieve tracking
and disturbance rejection simultaneously. The possible
fractional delay from discretization is also handled by
using a fractional delay filter. The stability conditions
and robustness analysis under model uncertainties are
provided. Two numerical examples including a supply
chain management (SCM) is provided to illustrate the
feasibility of the results.
