Abstract

In this paper, a newscheme to improve the performance of linear sampleddata systems is investigated by considering the time delay as a new control parameter, and the corresponding algorithm to determine the optimal parameter has been proposed based on the discrete-time approach. To clearly illustrate the proposed conclusions, the sampled-data system with time delay has been transformed into an augmented discrete-time system, which has been proven to be equivalent in terms of stability. Furthermore, a natural stability criterion based on the discrete-time system has been derived, enabling accurate computation of the maximum allowable sampling period for the systems under consideration. Additionally, an optimal time delay parameter solution algorithm has been proposed. Finally, two numerical examples are presented to certify the effectiveness and superiority of our theoretical results.
