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 interior of the unit circle of the z-plane, with the s-plane origin equating to z = 1 (because e = 1). A diagonal line of constant damping in the s-plane map… WebbRoot Locus Examples -- 2 598 views Nov 21, 2024 9 Dislike Share Save Syed Abdul Rahman Kashif 2.56K subscribers Two examples for the root locus sketch are discussed in … dnd pathfinder character creator outline
