WebMar 8, 2024 · RLOCFIND Find root locus gains for a given set of roots. [K,POLES] = RLOCFIND (SYS) is used for interactive gain selection from the root locus plot of the SISO system SYS generated by RLOCUS. RLOCFIND puts up a crosshair cursor in the graphics window which is used to select a pole location on an existing root locus. WebThe root locus plot indicates how the closed loop poles of a system vary with a system parameter (typically a gain, K). We can choose a value of 's' on this locus that will give us good results. The shape of the locus can also give us information on design of a more complex (lead/lag, PID controller) - though that wasn't discussed here.
Why make a root locus plot? - Erik Cheever
WebThe pink boxes on the root locus indicate the location of the closed-loop poles for the current loop gain. Clicking on the pink boxes and dragging them along the root locus to the desired location automatically modifies … WebPlot the root locus for this system, and then determine the closed-loop gain that gives an e ective damping ratio of 0.707. Solution: The root locus may be obtained by the commands: >> den = conv([1 3 0],[1 6 64]) den = 1 9 82 192 0 >> num = [0 0 0 0 1]; >> >> % set the range of gains fine enough to figure out the right gain >> % to get 0.707 ... breitlane executive search

WebNon-Standard Root Locus Problem 1. [FPE P5.14] For the feedback system shown in Figure 6, draw an equiv-alent block diagram where the gain K is multiplied directly by the open-loop plant. Using root locus, find the value of the gain K that results in dominant closed-loop poles with a damping ratio ζ = 0. 5. Figure 6: Feedback system. Answers ...
