How do you find the transfer function from a root locus plot?

The root locus exists on real axis to left of an odd number of poles and zeros of open loop transfer function, G(s)H(s), that are on the real axis. These real pole and zero locations are highlighted on diagram, along with the portion of the locus that exists on the real axis.

How to find settling time from root locus matlab?

In the Step Response plot, the settling time is around 0.05 seconds. To verify the exact settling time, right-click the Step Response plot area and select Characteristics > Settling Time. A settling time indicator appears on the response plot.

How do you find the stability of a root locus?

The root locus procedure should produce a graph of where the poles of the system are for all values of gain K. When any or all of the roots of D are in the unstable region, the system is unstable. When any of the roots are in the marginally stable region, the system is marginally stable (oscillatory).
