Breakaway and breaking points in root locus

WebDec 13, 2024 · Break in/away points: These exist when there are multiple roots on the root locus diagram. At the breakpoints gain K is either maximum and/or minimum. So, the roots of d K d s are the break points. Calculation: Given loop transfer function is, G ( s) = K s ( s + 3) 2 For breakaway points, d K d s = 0 ⇒ d d s [ s ( s + 3) 2] = 0 WebThe points where two real-axis root locus branches meet then leave the real axis are named the breakaway points. The gain K is minimum for break-in points and maximum …
