A standard linear time-delay system with a single constant delay is typically modeled using the state-space representation: Robust Control and Filtering for Time-Delay Sys...
For robust analysis, we often consider "norm-bounded uncertainties," where matrices Adcap A sub d are subject to variations ΔAcap delta cap A ΔAdcap delta cap A sub d 2. Stability Analysis: Lyapunov-Krasovskii vs. Razumikhin including the initial position of the state at time t = 0
