Root loci design using Dickson's technique

Determination of vertex polynomials to analyse robust stability of control systems with interval parameters

“…Nowadays, the analysis of the robust quality of control systems with interval parameters is also of great practical importance. There are some well‐known works where the root approach is proposed as the solution to the problem [27, 29, 31, 37–51]. It is worth mentioning that the proposed approach is quite simple and obvious for a designer.…”

“…However, there is a number of studies [38–42, 48] where the properties of the root locus developed by K. Theodorchik and W. Evans are applied.…”
