methods. Let the zero of the compensator be located at s = −15, and determine the compensator pole.

Determine the resulting system Kυ.

K G(s)= s(s+10)(s+50) We want the percent overshoot to be P.O. = 7.5% for a step input and the settling time (with a 2% criterion) of the system be T, = 400 ms. Find a suitable lead compensator by using root locus
