Comments, with reply, on "Estimating the robust dead time for closed-loop stability" by A.K. El-Sakkary

The commenters illustrate how easy it is to find the upper bound on the robust dead time for closed-loop stability as compared to a method for obtaining only its estimate, proposed in the above-mentioned paper (ibid., vol.33, no.6, p.599-601, June 1988). The author restates his main result and shows that it serves a purpose that was overlooked by the commenters.<
