First, based on a Lyapunov–Krasovskii Functional, delay-dependent FTS conditions are providedby introducing some free-weighting matrices. Then, a new reduced free-matrix-based inequality is established to estimatethe single summation term. The dimensions of these free matrices integral in our results are less than those obtained in theliterature. This reduction in the number of variables does not mean that our method is a particular case but simply that ourapproach is completely different from the others and therefore our method is more effective. Thus, less conservative designconditions are obtained in this paper in terms of linear matrix inequalities (LMIs) and solved using MATLAB’s LMItoolbox to achieve the desired performance. The purpose of this paper is to derive sufficient conditions that ensure thefinite-time stability of the discrete-time system. Finally, numerical examples are examined to show the advantage andeffectiveness of the proposed results.
