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.
