Robustness margin of the hot-dip galvanizing control system

This paper presents new results to compute the robustness margin of the hot-dip galvanizing control system. Compared to previous works on this issue, this paper considers a mathematical model of the plant with two inputs, used to control the system and one output. This paper bases its results on the value set characterization for interval plants with uncertain time delay along with the use of the zero exclusion principle to compute the robustness margin of the close loop system.
