WebSave 23K views 3 years ago Control Theory In this video we discuss how to sketch the root locus for a system by developing a series of 5 core rules augmented by 5 supplemental … Web8.5 Compensator Design by the Root Locus Method Sometimes one is able to improve control system specifications by changing the static gain only. It can be observed that as increases, the steady state errors decrease (assuming system’s asymptotic stability), but the maximum percent overshoot increases. However, using large values for may damage

WebConstruction of a Root Locus Diagram For 1+kG(s)H(s)=0, use the Root Locus Construction Rules (k!0) to sketch the root loci. 1. The number of Root Loci branches equals the order of the characteristic equation, max(n,m). 2. The Root Loci are symmetric with respect to the real axis of the s-plane. (In general, the root WebThe rules for constructing the root locus are as follows: Symmetricity of root locus The roots of the characteristic equation of the system can be either real, complex or combination of both. So, suppose we have n number of roots for K between 0 to infinity, the root locus on the s-plane must exhibit symmetricity about the real axis of the s-plane.
