Stability analysis for a class of networked/embedded control systems: A discrete-time approach

Abstract — Motivated by the widespread use of networked and embedded control systems, an algorithm for stability anal-ysis is proposed for sampled-data feedback control systems with uncertainly time-varying sampling intervals. The algorithm is based on the robustness of discrete-time systems against perturbation caused by the variation of sampling intervals. The validity of the algorithm is demonstrated by numerical examples. Index Terms — networked control systems, sampled-data sys-tems, quadratic stability, matrix exponential I
