- Classical control is applied to analysis of eigenvalue assignment with time-delay.
- Margins, Nyquist plots, and Padé approximations are compared with Taylor series.
- The primary eigenvalues are recovered quantitatively using a Padé approximation.
This note is a short discussion on the paper 'State feedback control with time delay', in which an a posteriori analysis on the primary closed-loop eigenvalues is proposed to ensure that the chosen location is accurately achieved by state feedback. The goal is twofold. First, a qualitative evaluation of closed-loop stability can be carried out by using classical control techniques, as systems margins or Nyquist plot, without the necessity of evaluating the primary closed-loop eigenvalues; and second, the well-known Padé approximants for time delay in frequency domain is shown to be as accurate as that the truncation of the Taylor exponential expansion proposed in that work.
