Consider a unity feedback control architecture where P(s) = 1/s^2 and C(s) = K * ((s + z)/(s + p)) . It is desired to design the controller to place the dominant closed-loop poles at sd = −2 ± 2j. Fix the pole of the compensator at −20 rad/sec and use root locus techniques to find values of z and...
