Second pole −p₂

Loop gain K

The root locus traces where a system's closed-loop poles travel as feedback gain increases. Poles in the left half-plane mean stability; as gain rises they migrate toward the imaginary axis, and crossing it triggers oscillation. Educational tool.

Governing equation

1 + \frac{K}{s ( s + p _{2} )} = 0 \Rightarrow s^{2} + 4 s + 3 = 0

Reading this result: Gain K=3 sits below the breakaway value, so both closed-loop poles stay real and negative near -2.00 — the response is overdamped with no oscillation.
