Suppose the unity feedback system of Fig. 5.60 has an open-loop plant given by G(s) = 1=s^2. Design a lead compensation D(s) = K (s + z)/(s+p) to be added in series with the plant so that the dominant poles of the closed-loop system are located at s = 2(+-)2j.
Note: this is a design problem and can have multiple solutions. try with p=20 and try to determine suitable value of z and k for the desired response using mat labs retool design toolbox
