Robust stability of dynamic predictor based control laws for input and state delay systems

• Robust stability analysis of the dynamic predictor scheme for state and input delay systems.
• Elegant frequency domain analysis.
• Robust stability bounds for matrix parameters, input or state delay uncertainties.
• Illustrative example showing conservative yet concordant bounds.

The robust stability properties of the dynamic predictor scheme for state and input delay systems are analyzed in the frequency domain. Robust stability bounds are presented for the cases of uncertainty of the matrix parameters, of the state or input delay, and of the combination of both. An example illustrates the results.
