What is Rlocfind in Matlab?

To find the gain at the point where the root locus intersects a line of constant damping ratio, the rlocfind function can be used, but the user has to manually select a point and Matlab finds the closest point on the root locus to the selection.

How do you find the root locus in Matlab?

In Control System Designer, a Root Locus Editor plot and input-output Step Response open. To view the open-loop frequency response and closed-loop step response simultaneously, click and drag the plots to the desired location. The app displays Bode Editor and Step Response plots side-by-side.

How do you find the angle of departure in Matlab?

The angle of departure can be calculated as 180-((sum of angles to a complex pole from the other poles)-(sum of angles to a complex pole from the zeros)).

How do you read a root locus plot?

Interpreting a Root Locus Diagram

If the real components of all poles are negative, then the system is said to be stable for that value of Kc. If the real component of the pole is positive, the system is unstable for that value of Kc, meaning the output signal will diverge from the set point.
