Fourth-Order Equation Triplex Research with Root Locus Methods

Abstract

Root locus was first used by American scientist Walter R. Evans to solve problems
of analysis and synthesis of automatic control systems. W. R. Evans
used Graph-analytical method to construct root locus. The Russian scientists
Tedorchik and his student Bendrikov also contributed to this study.
The article is the research of Triplex polynomials with one parameter using
Root Locus (RL). Roots movement trajectories analytic research revealed the
roots’ features that can not be detected graphically; In the article Triplex polynomials Root Locus is built.
