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. The plot of the root locus … See more • Phase margin • Routh–Hurwitz stability criterion • Nyquist stability criterion See more In addition to determining the stability of the system, the root locus can be used to design the damping ratio (ζ) and natural frequency (ωn) … See more The root locus of a feedback system is the graphical representation in the complex s-plane of the possible locations of its closed-loop poles for … See more Given the general closed-loop denominator rational polynomial the characteristic … See more • Ash, R.
