Splet1 + K 20(s+ 5) s(s2 + 2s+ 7) {z } s+1 j2:45 = 0 (2) In the process of sketching the root locus, I asked for the following: (a) Real-axis branches. As shown on the sketch, there is a real axis branch between the pole at s= 0 and the zero at s= 5. (b) Asymptote intersection and angle. Since there are 3 poles and 1 zero, there are 2 asymptotes. SpletYou can just try to calculate it directly: For α ≥ 1, we need to try the definition (analytical extension) of ∑k=1α k1 "appear" in the definition of ∑k=1α+1 k1 ...
