Web8 Dec 2013 · The root locus method of analysis is a process of of determining the points in the s plane satisfying the above two condition. Usually the forward path gain factor K is considered as an independent variable and the roots of 1+G (s)H (S) = 0 as dependent variables, the roots are plotted in s plane with K as a variable parameter. The root locus method can also be used for the analysis of sampled data systems by computing the root locus in the z-plane, the discrete counterpart of the s-plane. The equation z = e maps continuous s-plane poles (not zeros) into the z-domain, where T is the sampling period. The stable, left half s-plane maps into the … See more In control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system. … See more Using a few basic rules, the root locus method can plot the overall shape of the path (locus) traversed by the roots as the value of $${\displaystyle K}$$ varies.
